Question

Trinity donated 20% of her salary to charity and spent 10% of the remaining amount. She still has $22320 left. What is her total salary?

Answer 1

Answer:

$ 31,000

Step-by-step explanation:

Let Trinity's salary be $ x.

After donating 20% to charity,

Money left

= $x - \frac{20}{100}$×$x$

= $x - \frac{x}{5}$

= $\frac{4x}{5}$

Also, after spending 10% of the remaining,

Money left

= $\frac{4x}{5} - \frac{4x}{50}$

= $\frac{40x - 4x}{50}$

= $\frac{36x}{50} = \frac{18x}{25}$

Given that,

$\frac{18x}{25} = 22320$

$x = \frac{22320 X 25}{18}$

∴x = $ 31,000
