Answer:
$400000
Step-by-step explanation:
Let x equals her sales this year. Let y equal her sales last year. 60% of x is y. Lets write this into an equation.
x*.6=y
Input out known for y
x*.6=240000
To get x alone to find the sales this year, divide both sides by .6
(x*.6)/.6=240000/.6
Do the division
x=400000
She has $400000 in sales this year
