The ratio of the number of puffs to the number of scones in a kiosk is 5 : 1. A puff costs $1.40 and a scone costs $0.30. If all the puffs and scones are sold, a sum of $73 will be collected. How many puffs are there altogether?

Amount collected if all the puffs are sold
= 5 u x 1.4
= 7 u
Amount collected if all the scones are sold
= 1 u x 0.3 u
= 0.3 u
Amount collected if all the puffs and scones are sold
= 7 u + 0.3 u
= 7.3 u
7.3 u = 73
1 u = 73 ÷ 7.3 = 10
Total number of puffs
= 5 u
= 5 x 10
= 50
Answer(s): 50
