a.) Maddie works at a desighner store. She earns $1925 per month plus 10% commission of her sales. Write an equation to show how much she makes

b.) one month she earned $2725. Use your equation to show what her sales were that month

Please help, thanks :)

pay = 1925 + 0.10 * sales

2725 = 1925 + 0.10 * sales
0.10 * sales = 800
sales = 8000
