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
