Question

Sayir is saving his money for a laptop that costs 565.95. Right now he has 205.00, and can save 46.00 each week. How many weeks will it take for Sayir to have enough money to buy the laptop. Answer Choices: A: 6 weeks, B: 7 weeks, C: 8 weeks, D: 9 weeks

Answer 1

C: 8 weeks

Explanation:

Using the information provided in the question we can create the following model for this scenario. We have the total amount needed, an initial starting point of money he had already saved and the amount he is able to save each week which is multiplied by the variable number of weeks (x) which we need to solve for...

565.95 = 205.00 + 46.00x ... subtract 205.00 from both sides

360.95 = 46.00x ... divide both sides by 46.00

7.84 = x

We can now see that it would take Sayir a total of 7.84 weeks to save that money but since he gets paid on a weekly basis we would need to round up to 8 weeks.
