Answer:
$6.48
Explanation:
The discount is 10%. That means you pay 90% of the price.
At the regular price, 4 1/2 lb of bananas cost:
$1.60/lb * 4.5 lb = $7.20
Since with the 10% discount, you pay 90% of the original price, now we calculate 90% of the original price.
90% of $7.20 = 0.9 * $7.20 = $6.48
Answer: 4.5 lb cost $6.48 with the 10% discount
