on Saturday a bakery sold 6 cakes and several cupcakes a bakery made a total of 165 if Case sell for $12 each and cupcakes sell
for $3 each how many cupcakes did they sell
2 answers:
Cakes = x
Cupcakes = y
On Saturday, 6x + y = $165
We are told x = 12, so 6(12) + 3y = 165
72 + 3y = 165
Subtract the entire equation by 72:
3y = 93
Divide by 3 to simplify:
y = 31 cupcakes sold
$12•6=$72
$165-$72=$93
$93/$3= 31 cupcakes
Multiply $12 by the 6 cakes sold getting $72
Subtract $72 from the total $165 dollars made getting $93 left
Divide $93 by the $3 each cupcake cost getting 31 cupcakes
ANSWER: 31 cupcakes sold
