Define a variable ** Let x represent the number of cans Rachel brought in.
How many cans did Jaydon bring in? ** Jaydon:5+2x
How many cans did Mark bring in? ** Mark:4(5+2x)=20+8x
Write an equation ** Total:x+5+2x+20+8x=135
Combine like terms ** 11x+25=135
Subtract 10 ** 11x=110
Divide by 11 ** x=<<10=10>>10
How many cans did Mark bring in? ** Mark: 20+8(10)=100 cans
