at the cafe, Rebecca can choose to earn $10 per hour plus a $60 starting bonus or earn $12 per hour with no starting bonus. afte

qwelly [4]

Hi there! The answer is 30 hours.

Let the number of worked hours be represented by X.

The total earn of option 1, would then be 10X + 60
The total earn of option 2, would then be 12X

We end up with the following equation:
$10x + 60 = 12x$
Subtract 10X from both sides.

$60 = 2x$
Divide both sides by 2.

$x = 30$
Therefore, after 30 hours of work Rebecca will earn the same amount of money.
