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.
- Therefore: c+f=650
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.
- c+f=650
- 2.5c+1.5f=1195
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.
The number of candy bars sold is 220.
System of equations
In order to determine the number of candy bars sold, two simultaneous equations would be formed from the question.
2.50a + 1.50b = 1195 equation 1
a + b = 650 equation 2
Where:
- a = number of candy bars sold
- b = number of fruit snacks sold
Solving for the number of candy bars sold
In order to determine the number of candy bars sold, take the following steps:
Multiply equation 2 by 1.5
1.5a + 1.5b = 975 equation 3
Subtract equation 3 from 1
220 = a
