The skateboard that Jose wants costs $90. Jose has a coupon for
off the retail price. If Jose saves $18 a week, how long will it take to save enough to buy the skateboard?
A 3 weeks3 weeks
B 4 weeks4 weeks
C 5 weeks5 weeks
D 6 weeks6 weeks
E 7 weeks
C 5 weeks5 weeks
To find out how much Jose will have to save, we first need to calculate how much of a discount he will get with the coupon. If the coupon is for 10% off, Jose will save $9 since 0.10 x 90 = 9. This means he will pay $81 after the discount.
To find out how many weeks it will take for Jose to save $81, we divide the total amount he needs to save by his weekly savings: $81 / $18 = 4.5. Since Jose can't save for half a week, it would take him 5 weeks to save enough to buy the skateboard.
