Kazeer [188]

Answer:

y = $15.5x

Step-by-step explanation:

Given that

Tim earns $31 after 2 hours

$46.5 earns after 3 hours,

And, $62 earns after four hours

So first determine the each hour earnings i.e.

= $31 ÷ 2

= $15.5

In two hours it would be $31 and so on

So here the equation would be

y = $15.5x

Here

y = money amount

x = number of hours
