Let x = price for each cake and y = price of each pie in dollars.

We can get two equations out of the data. One from the Friday set, the other from the Saturday set.

**
**Then, we subtract both equations. The difference would be:

-20y = -160

y = -160 ÷ -20

y = $8

Finally, we substitute y to any of the equations. Suppose, we use equation 1:

30x + 20(8) = 460

30x = 460 – 160

30x = 300

x = 300 ÷ 30

x = $10

**Therefore, the cost for each cake and pie is $10 and $8, respectively.**
