The ratio of the number of croissants to the number of muffins in a shop is 5 : 1. A croissant costs $1.60 and a muffin costs $0.30. If all the croissants and muffins are sold, a sum of $166 will be collected. How many croissants are there altogether?

8 u |
0.3 u |
$166 |
Amount collected if all the croissants are sold
= 5 u x 1.6
= 8 u
Amount collected if all the muffins are sold
= 1 u x 0.3 u
= 0.3 u
Amount collected if all the croissants and muffins are sold
= 8 u + 0.3 u
= 8.3 u
8.3 u = 166
1 u = 166 ÷ 8.3 = 20
Total number of croissants
= 5 u
= 5 x 20
= 100
Answer(s): 100
