A grocery store sells brand A olive oil in a 33-fluid-once bottle for $16.50. The store also sells Brand B olive oil in a large
taurus [48]

Answer:

Brand A is the better buy with unit rate $4/cup.

Step-by-step explanation:

Given:

Brand A 33 fluid ounce bottle = $16.50

Brand B 1 cup = $4.80

We need to find the unit cost and find which is the better buy.

Solution:

For Brand A;

33 fluid ounce = $16.50

1 fluid ounce = Cost for 1 fluid ounce

By using Unitary method we get;

Cost for 1 fluid ounce = \frac{16.5}{33} = \$0.5

Now we know that;

1 cup = 8 fluid ounce.

1 fluid ounce = $0.5

8 fluid ounce = Cost for 8 fluid ounce of olive oil.

Again By using Unitary method we get;

Cost for 8 fluid ounce of olive oil = 0.5\times 8 =\$4

Hence Brand A 1 cup of olive oil cost $4.

For Brand B;

Given:

1 cup of olive oil =$4.80

Hence Brand B 1 cup of olive oil cost $4.8.

By Comparing both brands we can see that per unit cost of Brand A is less than Brand B.

Hence Brand A is the better buy.
