25 u - 10 |
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
= 6 u + 25 u - 10
= 31 u - 10
31 u - 10 = 176
31 u = 176 + 10
31 u = 186
1 u = 186 ÷ 31 = 6
Number of pastries that Warren sold
= 9 u + 10
= 9 x 6 + 10
= 54 + 10
= 64
Answer(s): 64
