Question

Tina has two part-time jobs.

- She earns $12 per hour working at a store.
- She earns $30 per lawn mowed working for a landscaper.
Her goal is to earn $1,800 to pay her monthly expenses.

The situation can be modeled by the formula below, where g represents the hours Tina works in the grocery store and m represents the number of lawns mowed.

1,800=12g+30m
After Tina learns how many hours she is scheduled to work in the grocery store, she has to figure out how many lawns she needs to mow that month.

Which equation shows the formula correctly rearranged to find m given g?


A. m = -5/2g + 1,800
B. m = -2/5g + 60
C. m = -5/2g + 150
D. m = -2/5g + 1800

Answer 1

To find the equation showing the formula rearranged to find m given g, you need to isolate 'm' on one side of the equation. The correct equation is m = (1,800 - 12g) / 30.

Step-by-step explanation:

To find the equation showing the formula rearranged to find m given g, we need to isolate 'm' on one side of the equation. Here are the steps:

Start with the original equation: 1,800 = 12g + 30m

Subtract 12g from both sides to isolate the term with 'm': 1,800 - 12g = 30m

Divide both sides by 30: (1,800 - 12g) / 30 = m

Simplify the expression on the right side, if needed.

The correct equation showing the formula rearranged to find m given g is m = (1,800 - 12g) / 30. Therefore, the answer is B. m = -2/5g + 1800.
