David earns $9.60 per hour for a 40-hour week. what was his net pay for a week in which his total deductions were $84.30?

$299.70

To find this, you need to find the gross pay or the pay without deductions. To find that, you need to multiply 9.60 with 40. You should get 384.

Now, subtract the deductions from the gross pay in order to find your net pay.

Hope this helps!

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
