The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x) . What is the sale price if the cereal cost $3.00?

Answer:
$2.40
Step-by-step explanation:
y = x - 20% of x
where x is $3.00
20% would be 1/5 of 3.00 = 3/5
3 - 3/5 = 15-3/5 = 12/5 = $2.40
Step-by-step explanation:
y = x - 0.2x
y = 0.8x
When x = $3.00, y = (0.8)($3.00) = $2.40.
The sale price is $2.40.
