The ratio of the number of macarons to the number of cookies in a kiosk is 6 : 1. A macaron costs $1.40 and a cookie costs $0.90. If all the macarons and cookies are sold, a sum of $93 will be collected. How many macarons are there altogether?

1 u |

| Value |
$1.40 |
$0.90 |
|
| Total value |
8.4 u |
0.9 u |
$93 |
Amount collected if all the macarons are sold
= 6 u x 1.4
= 8.4 u
Amount collected if all the cookies are sold
= 1 u x 0.9 u
= 0.9 u
Amount collected if all the macarons and cookies are sold
= 8.4 u + 0.9 u
= 9.3 u
9.3 u = 93
1 u = 93 ÷ 9.3 = 10
Total number of macarons
= 6 u
= 6 x 10
= 60
Answer(s): 60
