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