1 The deli charges $3.80 for a breakfast of 3 eggs & 4 bacon strips. The charge is $2.75 for 2 eggs & 3 bacon strips. Find the cost of each egg and the cost of each bacon strip?
let egg = $x
bacon = $y
3x+4y=3.80...............1
2x+3y=2.75...............2
3 x + 4 y = 3.8 .............1
2 x + 3 y = 2.75 .............2
multiply (1)by -2
Multiply (2) by 3
-6x-2y =-7.6
6x+3y=8.25
Add the two equations
y=0.65
Plug value of y in
3 x + 4 y = 3.8
3 x + 2.6 = 3.8
3 x + = 1.2
/ 3
x= 0.4
eggs 40 cents, bacon 65 cents
