Question

anonymous · Answer

Candy bars = B = 3
Cookies = C = 5

Max 20 Items x+y=20

XB + YC = 76

put the values for B and C in

3X + 5Y = 76
X + Y = 20

if X + Y = 20 then X = 20-y

insert into 3X + 5Y = 76

3(20-Y) + 5Y = 76

expand brackets

60-3Y + 5Y = 76

solve the rest of this equation and then put your answer into X + Y = 20 and you will have your answers
