To determine how much a customer will save per candy bar with the sale, follow these steps:
Step 1: Find the regular price of one candy bar.
The regular price is given as $0.75.
Step 2: Find the sale price of one candy bar.
Since three candy bars are sold for $1.50, divide the total sale price by the number of candy bars: $1.50 / 3 = $0.50.
Therefore, during the sale, one candy bar costs $0.50.
Step 3: Calculate the amount saved per candy bar.
To find how much a customer saves per candy bar, subtract the sale price from the regular price: $0.75 - $0.50 = $0.25.
Hence, a customer saves $0.25 per candy bar with the sale.
