Answer:
220 candy bars
Step-by-step explanation:
Let the number of candy bars sold=c
Let the number of fruit snacks sold=f
A total of 650 items were sold.
Candy bars are sold for $2.50
Fruit snacks are sold for $1.50
Total Income =$1,195
- Therefore: 2.5c+1.5f=1195
We solve the resulting system of equation for c, the number of candy bars sold.
From the first equation, f=650-c
Substitute f=650-c into 2.5c+1.5f=1195
2.5c+1.5(650-c)=1195
2.5c+975-1.5c=1195
Collect like terms
2.5c-1.5c=1195-975
c=220
Therefore, 220 candy bars were sold.
F(x) = 1.50x + 12.50
f(18) = 1.50(18) + 12.50
f(18) = 27 + 12.50
f(18) = 39.50 ....this is the amount Kelsey paid for 18 movies in 1 month
