The ratio of the number of muffins to the number of cookies in a kiosk is 6 : 1. A muffin costs $1.40 and a cookie costs $0.60. If all the muffins and cookies are sold, a sum of $360 will be collected. How many muffins are there altogether?

| Number |
6 u |
1 u |

| Value |
$1.40 |
$0.60 |
|
| Total value |
8.4 u |
0.6 u |
$360 |
Amount collected if all the muffins are sold
= 6 u x 1.4
= 8.4 u
Amount collected if all the cookies are sold
= 1 u x 0.6 u
= 0.6 u
Amount collected if all the muffins and cookies are sold
= 8.4 u + 0.6 u
= 9 u
9 u = 360
1 u = 360 ÷ 9 = 40
Total number of muffins
= 6 u
= 6 x 40
= 240
Answer(s): 240
