Question

Sophia, a resident of Metropolis, pays Metropolis an annual tax of $60 plus 1.4% of her
annual income. If Sophia paid $732 in tax, what was Sophia’s income?

 

I know $672 is 1.4% of her annual income,but i'm not sure how to create a formula for this to solve the rest of the problem.

Answer 1

Let x be her annual income

then 1.4% x = 672, or

.014x = 672

x = $48,000
