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?

John Snow · Answer 1

(1,800 - 12g) / 30 = m

Explanation:

$ 1,800 is her goal.

She earns $12 per hour working at a store.

She earns $30 per lawn mowed

g represents the hours Tina works in the grocery store

m represents the number of lawns mowed

Tina only needs to know the m value as she knows how many hours she is scheduled to work in the grocery store. So, we need to leave the m value alone in one side of the equation.
