Question

Terrell has $55. He saves an additional $10 each week. Which expression represents the total amount of money Terrell saves after w weeks?

Answer 1

m(w) = 10 +55w

1) Since Terrel has $55 and saves $10 per week, we can write a function for that, since $55 does not depend on anything but the value earned weekly depends on how many weeksTerrel can save it

m(w) = 55 +10w Where m stands for money

2) For example: If we want to know how much money Terrel can make it after ten weeks we just need to plug into that

m(10) = 55 + 10(10)

m(10) = 55 +100

m(10) = $155

3) So the expression that represents the total amount of money Terrell saves after w weeks is

m(w) = 10 +55w
