9 u - 14 |
The number of shortbreads at first is repeated. Make the number of shortbreads at first the same. LCM of 4 and 6 is 12.
Total number of pastries left
= 2 u + 9 u - 14
= 11 u - 14
11 u - 14 = 41
11 u = 41 + 14
11 u = 55
1 u = 55 ÷ 11 = 5
Number of pastries that Dylan sold
= 10 u + 14
= 10 x 5 + 14
= 50 + 14
= 64
Answer(s): 64
