The ratio of the number of croissants to the number of muffins in a supermarket is 6 : 1. A croissant costs $1.90 and a muffin costs $0.30. If all the croissants and muffins are sold, a sum of $468 will be collected. How many croissants are there altogether?

Total value |
11.4 u |
0.3 u |
$468 |
Amount collected if all the croissants are sold
= 6 u x 1.9
= 11.4 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
= 11.4 u + 0.3 u
= 11.7 u
11.7 u = 468
1 u = 468 ÷ 11.7 = 40
Total number of croissants
= 6 u
= 6 x 40
= 240
Answer(s): 240
