Reggie had some pastries.
37 of them were scones. The rest were muffins. He sold
25 of the scones and 17 muffins. In the end, he had 186 pastries left. How many pastries did he sell?

Scones |
Muffins |
Comparing pastries at first |
3x5 = 15 u |
4x5 = 20 u |
Before
|
5x3 = 15 u |
20 u |
Change
|
- 2x3 = - 6 u |
- 17 |
After
|
3x3 = 9 u |
20 u - 17 |
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
= 9 u + 20 u - 17
= 29 u - 17
29 u - 17 = 186
29 u = 186 + 17
29 u = 203
1 u = 203 ÷ 29 = 7
Number of pastries that Reggie sold
= 6 u + 17
= 6 x 7 + 17
= 42 + 17
= 59
Answer(s): 59
