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

Equation: y = 15.5x

Explanation:

Given that:

Time earns $31 for 2 hours

$46.5 for 3 hours

$62 for 4 hours

We will find unit rate first.

Unit rate =
`(31)/(2)` = $15.5 per hour

Now,

Let,

x be the number of hours

y be the total money earned by Tim

Total earning = Per hour rate * Number of hours

y = 15.5x

Hence,

Equation: y = 15.5x
