| Total value |
5.7 u |
0.4 u |
$244 |
Amount collected if all the macarons are sold
= 3 u x 1.9
= 5.7 u
Amount collected if all the croissants are sold
= 1 u x 0.4 u
= 0.4 u
Amount collected if all the macarons and croissants are sold
= 5.7 u + 0.4 u
= 6.1 u
6.1 u = 244
1 u = 244 ÷ 6.1 = 40
Total number of macarons
= 3 u
= 3 x 40
= 120
Answer(s): 120
