Question

Tonya made $65 less than four times Lily’s weekly salary. Write an algebraic expression to represent their combined salary.

Answer 1

C = t +L = 4L-65 + L = 5L -65

Combined salary = 5L -65 = 5 times Lilly's salary minus $65

or you could write it in terms of Tonya's salary

t=4L-65

4L = t+65

L = (t+65)/4

C = t+L = t+ t/4 +65/4 = 5t/4 +65/4

C = 5t/4 +65/4 = (5t+65)/4
