Question

Sarah went to the grocery store and bought 4 loaves of bread and 1 gallon of milk for $12. The next week, Sarah bought 2 loaves of bread and 3 gallons of milk for $13.50. Which system of equations below can be used to determine the cost of one loaf of bread (b) and one gallon of milk (m)?
A
4m × b = $12
2m × 3b = $13.50

B
4b × m = $12
2b × 3m = $13.50

C
4m + b = $12
2m + 3b = $13.50

D
4b + m = $12
2b + 3m = $13.50

Answer 1

Answer:

D.

Step-by-step explanation:

You want to add the totals for bread and milk together, you would not want to multiply.

Also, there were 4 loaves of bread bought, so 4m would be incorrect.

By process of elimination, we see that answer D is correct!
