Answer:
8 cups of lemonade
Step-by-step explanation:
Let us assume x be the number of bags of peanuts.
And, y be the number of cups of lemonade.
Now the equations are
0.35x + 0.75y= $7.05
And,
y = x+5
Now solve it 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
Now for
y = x+5
= 3+5
= 8
