Mathematics Middle School

A new seven – story apartment building is opening in our town. I was curious when I read the apartments on the higher floors were more expensive, so I went to the open house.

I discovered that there is only one very large apartment on the top floor. Each floor has twice as many apartments as the floor above it. The lowest floor contains only one-room studio apartments which are very small.

How many apartments are in this new building?

Find the generalized formula that would tell me how many apartments would be in this building if it had “X” stories?

Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?

Answers

Answer:

98%

Step-by-step explanation:

Test 1 - 83%

Test 2 - 91%

Test 3 - 88%

Test 4 - ?

If we use x to represent Test 4, we can create the following equation:

1/4 (83 + 91 + 88 + x) = 90

We find the average here by adding up the four test scores and dividing by 4.

Proceed to solve it:

1/4 (262 + x) = 90

262 + x = 360

x = 98

Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

$92.81

$82.27

$59.91

Answers

Answer:92.81

Step-by-step explanation:

Answer:

$82.27

Step-by-step explanation:

First, figure out how much it would be without tax.

(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25

Then, multiply this number by your tax rate.

77.25*6.5 = 5.02

Lastly, add your original total with this tax amount for your answer.

77.25+5.02= 82.27
