A student babysitting for$5 per hour writes the expression 5n to represent the money he makes for n hours. another student writes 3n 15 to represent the amount in dollars she makes. what is the second students hourly rate



Answer :

If 5 per hour makes 5n, then what per hour makes 3n? (per=multiply, n=number of hours, # per hour= hourly rate) Hint: look at the coefficient (number being multiplied by the variable, which in this case is n) for the hourly rate.
