Mrs. Martinez spent $15.25 buying candy for the 17 students in her Geometry class. If m&m's cost $0.75 and Snickers cost $1.00 how many of each did she buy?
1st step identify the variables x=m&m's y=Snickers
2nd Step Write 2 Equations x+y=170.75x+1.00y=15.25
3rd Step Solve the System using method of your choice SHOW ALL WORK
X+y-y=17-y
X=17-y
Substitute 0.75(17-y) +1.00y=15.25
12.75-.75y+1.00y=15.25
12.75+.25y=15.25
-12.75 -12.75
.25y=2.5
Divide by 25 y=10
Substitute x+10-17 x= 7
4th step Give your answer with labels 7 m&m's 10 Snickers
