25 u - 17 |
The number of scones at first is repeated. Make the number of scones at first the same. LCM of 3 and 5 is 15.
Total number of pastries left
= 9 u + 25 u - 17
= 34 u - 17
34 u - 17 = 289
34 u = 289 + 17
34 u = 306
1 u = 306 ÷ 34 = 9
Number of more scones than puffs that Dylan sold
= 6 u - 17
= 6 x 9 - 17
= 54 - 17
= 37
Answer(s): 37
