$8.5
1) Gathering the data
Cakes: $1.25
Loaves: $1.75
2) Let's pick different variables for loaves and cakes. Since they are different products.
1.25c + 1.75l
We're told to find the cost of 4 cakes and 2 loaves. Hence, we are going to plug that into this equation.
C= 1.25(4) +1.75(2)
C = 8.5
3) Hence, the cost of buying 4 cakes an 2 loaves is $8.5
