Question

You want to buy a pet iguana that costs ​$49. You already have ​$13 and you plan to save ​$9 per week. If w represents the number of weeks until you have enough money to buy the iguana​, what equation could you use to find the value of​ w? Use pencil and paper. Explain how you could set up an equation to find the amount of money you should save each week if you want to buy the iguana in six weeks.

Answer 1

Answer: 9w + 13 = 49; F

Explanation:

We can use the equation: 9w + 13 = 49, because 49 represents the total cost of the pet iguana, 13 represents how much you already have, and 9 represents how much money you're going to earn each week. The variable w = weeks. If you have two weeks, then you multiply 9 by 2 because each week you will earn 9 dollars.

In conclusion, the correct answer is F.
