Amy, Bruce, and Carlos collected a total of 168 pounds of cans to recycle. Bruce collected 1/3 the number of pounds of cans Carl

MakcuM [25]

Answer:

$c = 63\\b=21$

Step-by-step explanation:

Let number of pounds of cans collected by Amy = $a$

Let number of pounds of cans collected by Bruce = $b$

Let number of pounds of cans collected by Carlos = $c$

As per question statement, total number of cans collected = 168

$a+b+c=168$ ..... (1)

Number of pounds collected by Bruce is $\frac{1}{3}$ rd of the pounds of cans collected by Carlos.

$b = \dfrac{1}{3}c ..... (2)$

Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.

$a = b+c$

Using equation (2):

$a = \dfrac{1}{3}c +c \\\Rightarrow a =\dfrac{4}{3}c ..... (3)$

Using equations (2) and (3) in equation (1), we get:

$\dfrac{4}{3}c+\dfrac{1}{3}c+c =168\\\Rightarrow \dfrac{8}{3}c = 168\\\Rightarrow c =63$

Using equation (2):

$b = \dfrac{63}{3} = 21$
