Mrs. Martinez spent $15.25 buying candy for the 17 students in her G

eometry 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=17 0.75x+1.00y-15.25
3rd Step Solve the System using method of your choice SHOW ALL WORK
Xuy-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
