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 dispenser that customers can buy for $4.80 per cup.? Identify the unit cost for each and tell which is the better buy.

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 =

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 =

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.

BRAND A unit cost = $4

BRAND B unit cost = $4.8

We'll conclud that, BRAND A unit cost seems lesser than that of BRAND B. Hence it's the better buy

Step-by-step explanation:

BRAND A OLIVE OIL:

33-fluid-once bottle = $16.50

1 fluid-once bottle = $16.50/33

1 fluid-once bottle = $0.5

BRAND B OLIVE OIL:

1 Cup = $4.8

We would have just gone straight up and compare to the better buy from the values of their unit cost BUT, we observe that, the both olive oil are on different unit of measurements.

BRAND A OLIVE OIL is given in Fluid ounce

BRAND B OLIVE OIL is given in Cups

Our task here is to get a way to unify this difference.

Let's do this now; from standard it is known that:

1 cup = 8 fluid ounce.

Therefore,

1 cup = 8 fluid ounce

X cup = $ 0.5 fluid ounce

Cost for 8 fluid ounce in CUPS

= 8 * $0.5

= $4

NOW IT MEANS:

for BRAND A

1 cup cost $4

for BRAND B

1 cup cost $4.8

We'll conclud that, BRAND A unit cost seems lesser than that of BRAND B. Hence it's the better buy
