Fiona and her friends went to a smoothie shop. They ordered three strawberry smoothies and two protein shakes for a total of $24.00. Last week they ordered one strawberry smoothie and four protein shakes for a total of $25.50. The system that represents their purchases is below.

x + 4y = 25.50

3x + 2y = 24.00

What is the price of a protein shake?

$3.75
$4.50
$4.95
$5.25

Use elimination. Multiply the first equation by 3 and subtract the second:

3(x + 4y) = 76.50 → 3x + 12y = 76.50
Subtract 3x + 2y = 24.00 → 10y = 52.50 → y = 5.25

So a protein shake costs $5.25.
