2 Answers:

Choice B and Choice C

====================================================

Reasoning:

c = cost of one crate (some unknown amount in dollars)

c+20 = cost of a crate and a leash

5(c+20) = cost of five sets of items mentioned

5(c+20) = 475 is one equation we can form

5c+100 = 475 is another equation we can form

I used the distributive rule to go from 5(c+20) to 5c+100.

The 100 indicates that the five leashes combine to $100, since 5*20 = 100.

The 5c represents the cost of all five crates combined.

So 5c+100 is another way to express the total cost of all five crates and all five leashes.

---------------

Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.

The graph shows the relationship.....
Anna35 [415]

Answer:

Part A: That 6 pounds of rice costs $18

Part B: (1,3) represents the unit price

Part C: 4 pounds of rice, because $12/3 equals 4

Step-by-step explanation:

Part A: The first point, 6, is on the amount of rice axis and the second point, 18, is on the total cost axis.

Part B: The unit price means the price for just 1 of something, so if you go to 1 pound of rice on the graph, you see it's at 3 on the total cost axis. Which means that 1 pound of rice costs $3.

Part C: From Part B you know that 1 pound of rice equals $3. So if you spend $12, then you can divide that by $3 to see how many pounds of rice you bought. 12/3 equals 4, so you bought 4 pounds of rice. Or you can count by 3's until you get to 12: 3, 6, 9, 12. That's 4 times so that means you bought 4 pounds of rice.
