the table below shows the price of rolls at a bakery. a bakers dozen includes 13 rolls for the price of a dozen rolls. how much money is saved by buying a bakers dozen instead of 13 individual rolls?\n| number of rolls | 6 | 8 | bakers dozen |\n| price ($) | $3.60 | $4.80 | $7.20 |\n$0.55\n$0.60\n$0.70\n$0.75
Answer
# Explanation:
## Step1: Find price of 1 individual roll
First, find the price - per - roll when buying individual rolls. For 6 rolls at $3.60, the price per roll is $\frac{3.60}{6}=0.6$ dollars. For 8 rolls at $4.80, the price per roll is $\frac{4.80}{8}=0.6$ dollars. So the price of 1 individual roll is $0.6$ dollars.
## Step2: Calculate price of 13 individual rolls
The price of 13 individual rolls is $13\times0.6 = 7.8$ dollars.
## Step3: Calculate savings
The price of a baker's dozen is $7.20$ dollars. The savings is $7.8−7.20 = 0.60$ dollars.
# Answer:
$0.60$ dollars
