770¢ |
$1 = 100¢
$7.70 = 770¢
Amount paid if all were candy canes
= 14 x 40
= 560¢
Big difference between the amount paid for the candy canes and the mini cupcakes
= 770 - 560
= 210¢
Small difference between the amount paid for the one candy cane and one mini cupcake
= 70 - 40
= 30¢
Number of mini cupcakes
= 210 ÷ 30
= 7
