Jack bought 3 slices of cheese pizza and 4 slices of pepperoni pizza for a total cost of 12.50. sam bought 3 slices of cheese pizza and 2 slices of pepperoni pizza. what is the cost for one slice of pepperoni pizza?

$1.50

Step-by-step explanation:

Let cheese pizza be C and mushroom pizza be M

Given 3C+2B+4M+=+12.50

and

3C+2B+2M=8.50

Using elimination  

3C+2B+4+=12.50

3C+2B+2M=8.50

subtract the second equation from the first one to get

2M=4.00

Solve for M  

M+=+2.00 mushroom slice costs $2 each

Using that info, substitute for M in either equation to find C

3C+2B+2M=8.50

3C+2B+22A2=8.50

3C+2B+4=8.50

3C=4.50

C+=1.50

150 is the answer good luck
