Answer:
The equation is not true. It is actually c=30
Step-by-step explanation:
First you have to divide amount of money she's selling the candy bars for which is $2.50.
If her profit was $75, you want to know how much bars she sold, you will have to divide the amount of money she's selling the candy bars for and the amount she's earning which is $75 divided by $2.50 which is 30.
So c= 30
