5 u |
18 u - 16 |
The number of cookies at first is repeated. Make the number of cookies at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 16
= 23 u - 16
23 u - 16 = 191
23 u = 191 + 16
23 u = 207
1 u = 207 ÷ 23 = 9
Number of more cookies than cupcakes that Sean sold
= 25 u - 16
= 25 x 9 - 16
= 225 - 16
= 209
Answer(s): 209
