The remaining number of coupons before Zeph bought another 95 coupons is repeated. Make the remaining number of coupons the same. LCM of 4 and 5 is 20.
Total number of coupons at first = 35 u
Total number of coupons in the end = 8 u + 95
Number of coupons left was 14 more than the number of coupons at first.
35 u + 14 = 8 u + 95
35 u - 8 u = 95 - 14
27 u = 81
1 u = 81 ÷ 27 = 3
Total number of coupons at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
