Which of the following inequalities could you use to solve this problem? A. x < 750 B. x 750 C. 80x 750 D. 80x 750

Answer 1

`80x\geq 750`

She'll need to save at least 10 months to be able to go buy the computer.

Let

x ----> the number of months

we know that

The inequality that represent this situation is equal to

`80x\geq 750`

solve for x

`x\geq 750/80`

`x\geq 9.4\ months`

therefore

The minimum number of months is 10
