15 u - 19 |
The number of biscuits at first is repeated. Make the number of biscuits at first the same. LCM of 4 and 5 is 20.
Total number of pastries left
= 8 u + 15 u - 19
= 23 u - 19
23 u - 19 = 73
23 u = 73 + 19
23 u = 92
1 u = 92 ÷ 23 = 4
Number of more biscuits than muffins that Will sold
= 12 u - 19
= 12 x 4 - 19
= 48 - 19
= 29
Answer(s): 29
