Andre wants to save $40 to buy a gift for his dad. Andre’s neighbor will pay him weekly to mow the lawn, but Andre always gives
kirill115 [55]

Answer:

<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Cost of Andre's dad gift = $ 40

Weekly donation to the food bank = $ 2

Number of weeks to save $ 40 = 5

2. How much does Andre’s neighbor pay him each week to mow the lawn?

Let's calculate this amount, this way:

Weekly payment = [Cost of the gift + (Weekly donation * Number of weeks to save)]/Number of weeks

Replacing with the real values we know:

Weekly payment = [40 + (2 * 5)]/5

Weekly payment = 50/5 = 10

<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>
