Dawn has a 20% off one shirt coupon at her favorite store. If she buys 3 shirts at $29.99 each and uses her coupon, how much will her total bill be? Round to the nearest hundredth.

- $89.97
- $83.97
- $71.98
- $86.42

**Answer(s):** B

**Explanation:**

$83.97 is correct because $29.99 multiplied by 3 shirts is $89.97.

To get 20% off of ONE shirt, $29.99 is multiplied by 0.20, which equals $5.998.

You subtract $5.998 from $89.97 to get $83.972.

Rounded to the nearest hundredth you would get the correct answer, $83.97.

A number is 5 more than half of another number. How would you write this as a mathematical expression?

- (5 + 1/2)N
- N/5 × 2
- N/2 + 5
- N + 5/2

**Answer(s):** C

**Explanation:**

First, we let N represent any number.

We then express half of N as 1/2(N) or N/2

The phrase 5 more than indicates the mathematical expression 5+ Putting terms together, we get the correct answer.

|7| + |−2 | = ?

Note: This problem is the number -2 within an absolute value sign, not the number -21.

- 0
- 14
- 5
- 9

**Answer(s):** D

**Explanation:**

9 is the correct answer because the brackets around the numbers mean you are adding the absolute value of those numbers.

An absolute value looks at the actual number within the brackets and not any sign associated with it, including a negative sign. Therefore, 7 + 2 = 9.
