The ratio of the number of scones to the number of tarts in a kiosk is 4 : 1. A scone costs $1.10 and a tart costs $0.40. If all the scones and tarts are sold, a sum of $48 will be collected. How many scones are there altogether?

Amount collected if all the scones are sold
= 4 u x 1.1
= 4.4 u
Amount collected if all the tarts are sold
= 1 u x 0.4 u
= 0.4 u
Amount collected if all the scones and tarts are sold
= 4.4 u + 0.4 u
= 4.8 u
4.8 u = 48
1 u = 48 ÷ 4.8 = 10
Total number of scones
= 4 u
= 4 x 10
= 40
Answer(s): 40
