Answer:
The cost of 1 cupcake = $3.75.
Step-by-step explanation:
Let the cost of one cupcake = $ x.00
Now, the money spent by Cherie on 2 cupcakes = 2 ($x.00) = $2x
Also, the money spent by Sonya on 4 cupcakes = 4 ($x.00) = $4x
Now, according to the question:
$2x + $12.50 = $4x + $5.00
or, 2x + 12.50 = 4x + 5
⇒ 4x - 2x = 12.50 - 5
or, 2x = 7.50
or, x = 7.50/2 = 3.75
or, x = $3.75
Hence, the cost of 1 cupcake = $3.75.
