Question

14. On every 4th visit to the hair salon, Ms. Duke receives a discount of $5. On every 10th visit she receives a free hair product. After how many visits will Margot receive the discount and a free product at the same time? (numeric answer only) *

Answer 1

Answer:

20th visit

Step-by-step explanation:

4 and 10 both share 20 as the LCM.

and it'll be her 5th, consecutive 4th visit for the coupon and on that trip, because it's her 20th visit, it matches with every 10 visit's, therefore getting her both coupon's.
