The ratio of the number of croissants to the number of scones in a shop is 5 : 1. A croissant costs $1.70 and a scone costs $0.30. If all the croissants and scones are sold, a sum of $88 will be collected. How many croissants are there altogether?

Amount collected if all the croissants are sold
= 5 u x 1.7
= 8.5 u
Amount collected if all the scones are sold
= 1 u x 0.3 u
= 0.3 u
Amount collected if all the croissants and scones are sold
= 8.5 u + 0.3 u
= 8.8 u
8.8 u = 88
1 u = 88 ÷ 8.8 = 10
Total number of croissants
= 5 u
= 5 x 10
= 50
Answer(s): 50
