Question

Tim earns $31 after 2 hours, $46.5 after three hours,

and $62 after four hours. Write an equation that
represents the amount of money Tim makes.

Answer 1

Explanation:

The clue here is to determine how much he makes in 1 hour, then see if that amount works for 2 hours and 3 hours. If we know that he makes $31 in 2 hours, then 31/2 is $15.50. And $15.50 times 2 hours is $31, and $15.50 times 3 hours is $46.50. So the equation that represents the amount of money Tim makes is y = 15.5x, where y is the amount of money he makes when he works x number of hours at $15.50 per hour.
