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.
4m + b = $12
2m + 3b = $13.50
C.
4b + m = $12
2b + 3m = $13.50
D.
4b × m = $12
2b × 3m = $13.50

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
