<u>Answers</u>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47


<u>Explanation</u>

A fact family is a group of math facts using the same numbers.  In the case of addition/subtraction, you use three numbers and get four facts.

In this case we are going to write two different addition facts and two different subtraction facts as follows:

2.47,9.57,and 7.1

<em><u>Addition facts</u></em>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

<em><u>Subtraction</u></em>

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47

Which expression could be used to determine the cost of a $40 video game after a 15 percent discount?
LUCKY_DIMON [66]

Answer: The required expression is,

$ 40(0.85)

Step-by-step explanation:

Given,

The original cost of the videogame = $ 40,

Discount percentage = 15%,

So, the amount of discount = 15% of 40

= (0.15)40                     ( ∵ 1% = 0.01 )

Hence, the cost of the videogame = original cost - discount

= 40 - (0.15)40

= 40 (1-0.15)

= 40(0.85)

Which is the required expression .
