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

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!

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
