A store can buy 8 cartons of milk for $24 dollars or 7 cartons of milk for $28.

Question

How much less does each carton of milk cost if the store buys 8 cartons instead of 7 cartons?

A.$1 less

B.$2 less

C.$3 less

D.$4 less

Answer 1

We can start by finding the cost per carton in each scenario.

For 8 cartons at $24, we can set up the proportion:

8 cartons / $24 = 1 carton / x dollars

Solving for x, we get:

x = $3 per carton

For 7 cartons at $28, we can set up the same proportion:

7 cartons / $28 = 1 carton / y dollars

Solving for y, we get:

y = $4 per carton

Therefore, each carton costs $1 less if the store buys 8 cartons instead of 7.

Answer: A. $1 less
