Marcus is selling lemonade and peanuts. each cup of lemonade chats .75 and each bag of peanuts costs .35. on saturday marcus sold five more cups of lemonade than peanuts. he earned $7.05. how many cups of lemonade did marcus sell on saturday?

X=number of bags of peanuts.
y=number of cups of lemonade.
We suggest this system of equations.
0.35x+0.75y=7.05
y=x+5
solve by substitution method.
0.35x+0.75(x+5)=7.05
0.35x+0.75x+3.75=7.05
1.1x=7.05-3.75
1.1x=3.3
x=3.3/1.1=3

y=x+5
y=3+5=8


8 cups of lemonade

J= r + 9 because since jessica rode 9 more miles than roger, you add 9 miles to rogers mileage.
