12 pack of sodas she buy
Explanation of Solution
Given information:
Mrs. Gr wants to buy the package of soda that is less expensive per can.
Concept used:
A rate is a ratio of two quantities having different kinds of units. In unit rate it is simplified so that it has a denominator of 1. To express a rate as a unit rate, divide the numerator and denominator of the rate by the denominator.
Calculation:
A 6 pack of sodas is $2.20.
A 12 pack of sodas is $4.25.
Express each rate as a unit rate.
A 6 pack of sodas is $2.20.
Here rate is
A 12 pack of sodas is $4.25.
Here rate is
Less expensive pack is 12 pack of sodas.
Hence, 12 pack of sodas she buy.
