mark is going to work for his father’s pool cleaning business during the summer. mark’s father will pay him $5 each pool he help
s clean. write an algebraic expression to determine how much mark will earn if he cleans n pools. then evaluate the expression for 15, 25, 35, or 45 pools
If <em>n</em> represents the amount of pools Mark has cleaned, and he earns $5 for each pool, then 5n will be the algebraic expression. As <em>n</em> represents the number of pools he has cleaned, we need to <u>plug in</u> the given numbers to get the answer, hence [5(15), 5(25), 5(35), 5(45)]. Multiply $5 by the given numbers to get the amount of money Mark would earn if he cleaned the amount of pools.
