Anne, Ryan and Joel collect empty cans. They collect a total of 1925 cans. Anne collects half as many as Ryan. Joel collects twice as many cans as Ryan. How many cans does Joel collect? Use bar model to solve.

Bar model???

standard way:
Ryan ----- x cans
Anne ----- x/2 cans
Joel ------ 2x cans

x + x/2 + 2x = 1925
(7/2)x = 1925
x = 550

take over

To solve this problem using a bar model, we need to represent the information given and find the number of cans Joel collects.

Let's start by identifying the unknown quantities and representing them with variables:
- Number of cans Ryan collects = R
- Number of cans Anne collects = 1/2R (half as many as Ryan)
- Number of cans Joel collects = 2R (twice as many as Ryan)

We know that the total number of cans collected by Anne, Ryan, and Joel is 1925, so we can set up an equation:

R + 1/2R + 2R = 1925

Now, let's solve the equation step by step:

Combining like terms, we have:
5/2R = 1925

To isolate R, we can multiply both sides by 2/5:
R = 1925 * 2/5 = 770

Now that we know R, we can find the number of cans Joel collects:
Number of cans Joel collects = 2R = 2 * 770 = 1540

Therefore, Joel collects 1540 cans.
