Introduction

Johnny, a hardworking individual, earns $\$850$ per week. However, his earnings are subject to certain deductions, including insurance and taxes. In this article, we will delve into the mathematical aspects of Johnny's paycheck, exploring the fraction of his earnings that are spent before he receives his full amount.

Calculating Insurance Deductions

First, let's calculate the amount Johnny pays for insurance. He pays $\$100$ for insurance, which is a fixed amount deducted from his earnings.

Insurance Deduction = $100

Calculating Tax Deductions

Next, we need to calculate the tax deductions. Johnny gets taxed $8\%$ on the rest of his earnings, which is the amount remaining after the insurance deduction. To calculate the tax deductions, we need to find the amount remaining after the insurance deduction.

Remaining Earnings = $850 - $100 = $750
Tax Rate = 8% = 0.08
Tax Deduction = Remaining Earnings x Tax Rate
Tax Deduction = $750 x 0.08 = $60

Calculating Total Deductions

Now, let's calculate the total deductions, including insurance and taxes.

Total Deductions = Insurance Deduction + Tax Deduction
Total Deductions = $100 + $60 = $160

Calculating the Fraction of Earnings Spent

To find the fraction of Johnny's paycheck that has been spent before he receives it, we need to divide the total deductions by his earnings.

Fraction of Earnings Spent = Total Deductions / Earnings
Fraction of Earnings Spent = $160 / $850
Fraction of Earnings Spent = 0.1882 (or approximately 18.82%)

Conclusion

In conclusion, Johnny's paycheck is subject to certain deductions, including insurance and taxes. By analyzing these deductions, we can determine the fraction of his earnings that are spent before he receives his full amount. In this case, approximately $18.82\%$ of Johnny's paycheck is spent before he receives it.

Answer

The correct answer is $\boxed{\frac{160}{850}}$ .

Discussion

This problem requires a basic understanding of mathematical concepts, including percentages and fractions. The solution involves calculating the total deductions, including insurance and taxes, and then dividing that amount by Johnny's earnings to find the fraction of his paycheck that has been spent.

Solutions

A person earns $\$1200$ per week and pays $5\%$ tax on their earnings. The tax deduction is $$1200 x 0.05 = $60$ . The fraction of their paycheck spent on taxes is $\frac{60}{1200} = \frac{1}{20}$ .
A person earns $\$900$ per week and pays $\$50$ for insurance. The fraction of their paycheck spent on insurance is $\frac{50}{900} = \frac{1}{18}$ .
