The ratio of the number of muffins to the number of cupcakes in a stall is 5 : 1. A muffin costs $1.60 and a cupcake costs $0.80. If all the muffins and cupcakes are sold, a sum of $88 will be collected. How many muffins are there altogether?

| Value |
$1.60 |
$0.80 |

| Total value |
8 u |
0.8 u |
$88 |
Amount collected if all the muffins are sold
= 5 u x 1.6
= 8 u
Amount collected if all the cupcakes are sold
= 1 u x 0.8 u
= 0.8 u
Amount collected if all the muffins and cupcakes are sold
= 8 u + 0.8 u
= 8.8 u
8.8 u = 88
1 u = 88 ÷ 8.8 = 10
Total number of muffins
= 5 u
= 5 x 10
= 50
Answer(s): 50
