trinas paycheck earnings varies directly as the umber of hours she works, if she works 19 hours and earns $187.15, what should she earn if she worked 40 hours

Answer 1

To find out what she should earn if she worked 40 hours, we can set up a proportion based on the given information.

Let x be the amount she should earn if she worked 40 hours.

We can set up the proportion as follows:

19 hours / $187.15 = 40 hours / x

To solve for x, we can cross-multiply:

19x = 187.15 * 40

19x = 7486

Divide both sides by 19:

x = 7486 / 19

x ≈ $393.47

Therefore, she should earn approximately $393.47 if she worked 40 hours.
