In a system of equations with two variables, you generally need two equations to find a unique solution, and this system is no exception. One example of a solution to this problem is (1, 2), but (3, 9) and (5, 16) also work, and there are actually infinitely many solutions to this single equation.

Well to find the total sales you must substitute for the variable in the equation;

t = 68.95b

t = 68.95(31)

t = 2,137.45

So the total of the store's boot sales is;

**$2,137.45**

Given Situation:
Majed bought a new pair of jeans. After the 15% sales tax the price became 11.50 dollars.
Let’s start solving to find the original price of the jeans Majed bought.
=> 15% = 15 / 100 = .15
=> 10 dollars * .15 = 1.5 dollars.
Now, let’s add this production to get the total amount that Majed paid.
=> 10 + 1.5 = 11.5 dollars
=> 10 is the original price of the jeans plus the 15% sales tax, total is 11.5 dollars

Lana gets the 7 points so she ends up with 331. She will then be 358-331=27points behind Emily. She needs to win, so there needs to be 1 more than 27 points of change in the score, or 28 points. Emily's hand value is added to Lana's and also subtracted from Emily's so her hand is worth twice the value as the amount. (If the hand is worth 10 points, it changes the scores by 20 points). Thus, we only need half of the 28 points of change for Lana to win. The answer is 14 points.

44,000 people is 100% of the attendance value, so you would need to guess within a 90-110% range of the actual value (90% is 10 less than 100% and 110% is 10 more than 100%). To get the number of people in the range, you need to multiply. 44,000×0.9=39,600 people. 44,000×1.1=48,400. So the range your guess would have to be in is 39,600-48,400 people.

QUESTION POSTED AT 14/12/2019 - 08:29 AM

**Answer:**

The total cost Henry spends are $236.36 .

The total rain fall during the week is 5.83 in .

The amount left in the account is $180.68 .

**Step-by-step explanation:**

**First part**

As given

Henry was buying clothing for the fall at Good Stuff.

He spent $59 on a pair of jeans, $45.87 on a shirt, and $131.39 on a pair of shoes.

Total henry spends = Cost of the pair of jeans + Cost of the shirt + Cost of pair of shoes

Put all the values in the above

Total henry spends = $59 + $45.87 + $131.39

= $236.36

Therefore the total cost Henry spends are $236.36 .

**Second part **

As given

The rain totals for one week in Indiana in November were: 2 in., 0.58 in., 0 in., 0.2 in., 0 in., 0.9 in., and 2.15 in.

Total rain fall during the week = 2 + 0 + 0.58 + 0.2 + 0 + 0.9 + 2.15

= 5.83 in

Therefore the total rain fall during the week is 5.83 in .

**Third part **

Your checking account has a beginning balance of $68.02.

You deposited $169.23 into the account.

The next week you spent $31.57 for gas and $25 to go out with friends.

Amount left in the account = Beginning balance + Deposited amount - Amount spent on gas - Amount spends on go out with friends.

Put all the values in the above

Amount left in the account = 68.02 + 169.23 - 31.57 - 25

= 237.25 - 56.57

= $ 180.68

Therefore the amount left in the account is $180.68 .

To find a percentage increase of 15%, you can multiply the original value by 1.15.

To find a percentage increase of 20%, you can multiply the original value by 1.2.

117.7 * 1.15 = 135.355

So if she orders 15% extra tile, she will order around about 135.355 square feet.

117.2 * 1.2 = 141.24

And if she orders 20% extra tile, she will order around about 141.24 square feet.

Any number between those two values will be the amount of tile she might order.

To find this...we need to see how much the total AMOUNT is.

N is for nickels and Q is for Quarters.

n+q=20 would be our first equation.

We could see which choices have this as the first equation and cross the rest of the others out.

B and D have this...so we are left with those two choices.

n+q=20

Since we do not know how many nickels and quarters there are, we already know how much each is worth.

Since we have that info, we can write a second equation.

5n+25q=4.00

Now their is only one answer that states this.

**Our final answer is that (D) n+q=20 5n+25q=400 is our answer.**

Without doing the math, you can tell the answer is A.

50% of 120 pencils is 60 pencils. From there you just use process of elimination. It can't be B because there are over 50% black pencils. There aren't enough pencils in total for the answer to be C and not all penciled are black, so it can't possibly be D. That leaves us with A which is quite close to 50%.

Another method would be multiplying 120 by 60% (round 59%), which equals 72 pencils (A)
