B. Use the equation to determine how much money Kara can save in 24 weeks

Answer 1

number of weeks
A = total amount of saved over w weeks

A = 20 + 15(w - 1)

b. Use the equation to determine how much money Kara can save in 24 weeks.

A = 20 + 15(w - 1)

A = 20 + 15(24 - 1)

A = 20 + 15(23)

A = 20 + 345

A = $365 Amount Saved in 24 Weeks
