Question

Dexter has a gift card for $20.00 to an electronics store. He also has a coupon for 25% off his entire purchase, so he will be paying 75% of the total cost. He plans to buy a video game for $10.00 and batteries for $2.00. Select the equation that represents how much money will be left on his gift card after his purchases if x represents his remaining balance.

What is the equation that represents his remaining balance?

Answer 1

The linear equation that represent the situation is
`x=20-0.75(10+2)`

The remaining balance on his gift card is $11

Explanation:

Let x represent the remaining balance.

We know that the linear equation that represent the situation is equal to
`x=20-0.75(10+2)`

Solve

`x=20-0.75(12)`

`x=20-9`

x=$11

Answer 2

Explanation:

x=20(.75)+2+10 (or 12 if it says that)
