16 u - 3 |
The number of muffins at first is repeated. Make the number of muffins at first the same. LCM of 3 and 4 is 12.
Total number of pastries left
= 3 u + 16 u - 3
= 19 u - 3
19 u - 3 = 54
19 u = 54 + 3
19 u = 57
1 u = 57 ÷ 19 = 3
Number of more muffins than tarts that Henry sold
= 9 u - 3
= 9 x 3 - 3
= 27 - 3
= 24
Answer(s): 24
