Can someone please explain these two math questions to me, please?

1. Given the pay rate, hours worked, tax deductions, and social security deduction, determine the gross earnings, worker's compensation insurance (assuming 2% of gross earnings), state unemployment insurance (assuming 4% of gross earnings), total deductions, and net pay.

2. Given the pay rate, hours worked, tax deductions, and social security deduction, determine the gross earnings, group health insurance (assuming 15% of gross earnings), pension deduction (assuming 6.5% of gross earnings), total deductions, and net pay.

I already found out the gross earnings, but the rest is confusing. Thanx!
