Each Club member collected 15 boxes of recycling for community service. Let c represent the number of club members and T represents two total number of boxes collected. Which equation models the situation?

Answer: If each member of the club collected 15 boxes, and you have C members in your club, then the total amount of boxes collected is 15*C boxes.

if you wanted to write "the" instead of "two"; then T = 15*C.

if you wanted to write "twice" instead of "two"; then T = 2*15*C = 30*C.

The equation is (assuming you meant the instead of two) : T = 15c
