Explain how a system of equations can

be used to find a flat fee and a perĀunit rate.

Suppose,X is the flat fee and Y is per unit ratelets assume X is your fixed pay, and Y is the overtime amount you get per hour,so, if a equation say that on working 3 hours extra, earning was 130 andon working 5 hours extra the earning was 150.so, the equations will be...X + 3Y =130X +5y = 150if you solve these by elimiantion,X+3Y - (X+5Y) = 130-150or, X-X +3Y - 5Y = -20or, -2Y =-20or, Y=10and X+3*10=130or, X=130-30 = 100so, the fixed pay is 100 and 10 is per unit rate.Hope this helps. Please best my answer and message me if you have any doubts :)
