Ella uses 0.5 pound of raspberries in each raspberry cake that she makes. how many cakes can she make with 3.25 pounds of raspberries?

b. if each pound of raspberries cost $2.39, how much did she pay for them?

Well for part a. the answer is 6.5 because 3.25 divided by 0.5 is 6.5

Another ratio and proportion problem

they are in propoertion

0.5lb for 1 cake

how many cakes for 3.25lb?

numberofcakes:weight=1/0.5

we want to find how many for 3.25

x/3.25=1/0.5

times both sides by (0.5) (3.25)

0.5x=3.25

divide both sides by 0.5 aka times 2 to both sides

x=6.5

6.5 cakes can be made

b. each lb costs 2.39

easy

total cost=cost per 1 times how many lb

totl cost=2.39 tiesm 3.25

total cost=7.767, rounded

total cost=$7.77

A. 6.5 cakes

B $7.77
