Amy, Bruce and Carlos collected a total of 168 pounds of cans to recycle. Bruce collected 1/3 the number of pounds of cans Carlo
s collected. Amy collected the same number of pounds of cans as Bruce and Carlos combined. Let c represent the number of pounds of cans Carlos collected. Write an equation, in terms of c, that expression the relationship between the number of pounds of can collected by each student and the total weight of the cans collected. I just need help setting up an equation. I already found out what they each collected.
Using a proportion to solve this, we write the scale factor as a ratio first: 19/38, since 19 is the size of the model's length and 38 is the real length. For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:
