The graph shows the cost C in dollars of w pounds of blueberries, a proportional relationship. Select all the true statements.

A. 1 pound of blueberries costs $2.75.
A. 1 pound of blueberries costs $2.75.

B. 2.75 pounds of blueberries cost $1.
B. 2.75 pounds of blueberries cost $1.

C. 12 pounds of blueberries cost $15.50.
C. 12 pounds of blueberries cost $15.50.

D. 12 pounds of blueberries cost $33.

A, D

Step-by-step explanation:

Cost ($) = C

lbs (Blueberries) = W

One pound of blueberries costs $2.75 because to find how much 1 lb is you need to divide by 6.

6 is the number of pounds at that point in the graph, so you divide both the pounds and cost by 6 to find how much 1 lb is.

To find how much 5 lbs costs, multiply both the cost and number of pounds ($2.75 to 1 lb) by 5.

2.75 * 5 is 13.75 (This means C is wrong)

Do the same but with 12 for D

2.75 * 12 is 33, so D is correct

You could do the same method as above for E, but the easier way to do this is to see that the relationship of 3:9 is equal to a 1:3 ratio, which is the same as what the pounds to cost ratio is (which is 1:2.75)

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
