Question

Oliver needs to save at least $1500 to buy a computer. He has already saved $650. How much more does he need to save? Write and solve an inequality.

A) x + 650 ≥ 1500; x ≥ 850
B) x + 650 ≤ 1500; x ≤ 850
C) x + 1500 ≤ 650; x ≤ -850
D) x + 1500 ≥ 650; x ≥ -850

Answer 1

The answer is A: x + 650 ≥ 1500; x ≥ 850.

Answer 2

A

Explanation:

IF Oliver needs to save at least $1500, he has the to save $1500 or more. The expression we can write with x being the amount he needs to save:

x+650≥1500

We can solve x by taking 650 to the left side of the inequality:

x≥1500-650

x≥850

The answer is A, Oliver needs to save more than 850 to have total savings of at least $1500
