Answer:
The cost of each candy bar is $1.5.
Step-by-step explanation:
Consider the provided information.
You set a personal goal of raising $200 for your school and met that goal. You sold a total of 120 candy bars and one neighbor gave you a 20 donation without taking any candy bars.
Let the cost of candy bars represented by x.
You sold a total of 120 candy bars.
The cost of 120 candy bars is: 120x
Your neighbor gave you a $20 donation and you met that goal.
Therefore, the required equation will be: [tex]120x+20=200[/tex]
Now solve the above equation as shown below:
[tex]120x+20=200[/tex]
[tex]120x=200-20[/tex]
[tex]120x=180[/tex]
[tex]\frac{120x}{120}=\frac{180}{120}[/tex]
[tex]x=1.5[/tex]
Hence, the cost of each candy bar is $1.5.
