B. 4 weeks
To calculate the amount Jose will need to save after applying the coupon, you need to subtract 1/5 off of $90:
$90 x 1/5 = $18
So, Jose will need to pay $90 - $18 = $72 for the skateboard.
Since Jose saves $18 a week, it will take him $72 / $18 = 4 weeks to save enough to buy the skateboard.
The skateboard that Jose wants costs $90. Jose has a coupon for 1/5 off the retail price. If Jose saves $18 a week, how long will it take to save enough to buy the skateboard?
A. 3 weeks
B. 4 weeks
C. 5 weeks
D. 6 weeks
E. 7 weeks
