Charmaine is saving money to buy a bike. She has and is going to save an additional each week. The bike costs . In how many weeks will she have enough money to buy the bike?
(a) Write an equation that could be used to answer the question above. First, choose the appropriate form. Then, fill in the blanks with the numbers 60,5 , and 125 . Let represent the number of weeks.
(b) Solve the equation in part (a) to find the number of weeks.
w =
a) The appropriate form for the equation is:
60 + 5w = 125
b) To solve for the number of weeks, we need to isolate the variable w.
Subtract 60 from both sides:
5w = 65
Divide both sides by 5:
w = 13
Therefore, Charmaine will have enough money to buy the bike in 13 weeks.
