Write an equation to represent the situation. Then, solve the equation.Angela's salary started at $38,000 per year with annual raises of $3000. Stanly's salary started at $44,000 with annual raises of $2000. Angela and Stany were hired at the same time. After how many years will both employees earn the same salary?
A. $38,000x + $3000 = $44,000x + $2000; 6 years B. $38,000 + $2000x = $44,000 + $3000x; 6 years C. $38,000 + $3000x = $44,000 + $2000x; 6 years D. $38,000x + $2000 = $44,000x + $3000; 6 years
