| Total value |
7.8 u |
0.6 u |
$252 |
Amount collected if all the croissants are sold
= 6 u x 1.3
= 7.8 u
Amount collected if all the muffins are sold
= 1 u x 0.6 u
= 0.6 u
Amount collected if all the croissants and muffins are sold
= 7.8 u + 0.6 u
= 8.4 u
8.4 u = 252
1 u = 252 ÷ 8.4 = 30
Total number of croissants
= 6 u
= 6 x 30
= 180
Answer(s): 180
