Question

A man pays 20 percent of his total income in tax. His weekly tax is $100. What is his total weekly income?

Answer 1

Hey there,
100% = $100
1% = 100 / 100
= $1
20 % = 20 x $1
= $20
Weekly Income = $100 - $20
= $80

Hope this helps :))

Answer 2

$500

Explanation:

A man pays 20% of his total income in tax.

His weekly tax = $100

Let his total weekly income = x

He pays income tax = 20% of x = 100

= 0.20x = 100

x = 100 ÷ 0.20

= 500

His total weekly income is $500.
