18 u - 6 |
The number of scones at first is repeated. Make the number of scones at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 6
= 23 u - 6
23 u - 6 = 201
23 u = 201 + 6
23 u = 207
1 u = 207 ÷ 23 = 9
Number of pastries that John sold
= 25 u + 6
= 25 x 9 + 6
= 225 + 6
= 231
Answer(s): 231
