The remaining number of coupons before Bobby bought another 94 coupons is repeated. Make the remaining number of coupons the same. LCM of 3 and 8 is 24.
Total number of coupons at first = 40 u
Total number of coupons in the end = 15 u + 94
Number of coupons left was 44 more than the number of coupons at first.
40 u + 44 = 15 u + 94
40 u - 15 u = 94 - 44
25 u = 50
1 u = 50 ÷ 25 = 2
Total number of coupons at first
= 40 u
= 40 x 2
= 80
Answer(s): 80
