Answer:

A. x>=28 (x is greater than or equal to 28)

Step-by-step explanation:

She needs $200. She already has $60. So, she has to make 200-60 = $140

If she earns $5 per hour,

she has to work for x hours such that,

5x >= 140

Divide by 5,

x >= 28

Answer:

A. x ≥ 28

Step-by-step explanation:

First, we need an equation:

200 ≤ 5x + 60

Basically, she needs at least (the same amount or greater) 200 dollars. She already has 60, and earns 5 dollars an hour. 5x = amount earned per hour + the 60 she already has

Then we solve!

(equation) 200 ≤ 5x + 60

(subtract 60 from both sides) 140 ≤ 5x

(divide both sides by 5, it is not a negative so no flipping the sign) 28 ≤ x

(answer) x ≥ 28
