Answer:

C

Step-by-step explanation:

First, in order to find the lowest price, you have to find the cost for 1 can in each store.

Save Rite: Since it is $ 5.25 for 3 cans, you divide 5.25 by 3. The quotient is 1.75. So, the price is $ 1.75 per can.

Then you do the same for Spend Less.

Spend Less: Since it is $ 7.50 for 5 cans, you divide 7.5 by 5. The quotient is 1.5. So, the price is $ 1.50 per can.

Since Save Rite's price for one can is $ 0.25 more than Spend Less, it is more expensive.  

So in order to see how much she paid for 15 cans from the cheapest store, you would have to multiply 15 by 1.5.

The answer is 22.50.

The answer is C

Maria pays $22.5 for buying 15 cans of cat food.

What is a word problem?

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

At Save Rite,

Cost of cat food = $5.25 for 3 cans

Then, cost of of cat food per can = [tex]\frac{5.25}{3}[/tex]

⇒ [tex]\$1.75[/tex]

Spend Less,

Cost of cat food = $7.50 for 5 cans

Then, cost of of cat food per can = [tex]\frac{7.50}{5}[/tex]

⇒ [tex]\$1.50[/tex]

Now, [tex]1.75 > 1.50[/tex]

So, the store with the lowest price is spend less.

Thus price for 15 cans is

⇒ [tex]15(1.5)=22.5[/tex]

Hence we can conclude that Maria pays $22.5 for buying 15 cans of cat food.
