9 u - 10 |
The number of croissants at first is repeated. Make the number of croissants at first the same. LCM of 4 and 6 is 12.
Total number of pastries left
= 2 u + 9 u - 10
= 11 u - 10
11 u - 10 = 23
11 u = 23 + 10
11 u = 33
1 u = 33 ÷ 11 = 3
Number of more croissants than cupcakes that Bryan sold
= 10 u - 10
= 10 x 3 - 10
= 30 - 10
= 20
Answer(s): 20
