The remaining number of coupons before John bought another 46 coupons is repeated. Make the remaining number of coupons the same. LCM of 2 and 5 is 10.
Total number of coupons at first = 25 u
Total number of coupons in the end = 6 u + 46
Number of coupons left was 8 more than the number of coupons at first.
25 u + 8 = 6 u + 46
25 u - 6 u = 46 - 8
19 u = 38
1 u = 38 ÷ 19 = 2
Total number of coupons at first
= 25 u
= 25 x 2
= 50
Answer(s): 50
