Question

Joel bought 3 cupcakes and 1 loaf of bread from the bakery for $5.60. Irfan bought 2 cupcakes and 2 loaves of bread from the same bakery for $6.40. How much did each cupcake cost?

Answer 1

Answer:

$1.20

Step-by-step explanation:

Let the cost of a cupcake be c and the cost of a loaf of bread be b.

This means that 3c+b=5.60 and 2c+2b=6.40.

The second equation implies that c+b=3.20.

Subtracting this from the first equation yields 2c=2.40, and thus c=1.20.
