The number of tarts at first is repeated. Make the number of tarts at first the same. LCM of 5 and 6 is 30.
Total number of pastries left
= 5 u + 18 u - 13
= 23 u - 13
23 u - 13 = 171
23 u = 171 + 13
23 u = 184
1 u = 184 ÷ 23 = 8
Number of more tarts than scones that Perry sold
= 25 u - 13
= 25 x 8 - 13
= 200 - 13
= 187
Answer(s): 187
