Answer:
The difference in the unit rates of the jars of peanut butter is 0.4.
Step-by-step explanation:
In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:
27.12/8=3.39
26.53/7=3.79
Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:
3.79-3.39=0.4
According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.
