Brad sold candy bars and cookies for a fundraiser at school. Candy bars sold for $3, and cookies sold for $5. He sold a total of
kari74 [83]

Answer: First option

12 candy bars were sold

Step-by-step explanation:

Call x the amount of candy sold and call z the amount of cookies sold. Then we know that

x + z = 20

We also know that candy bars sell for $ 3 and cookies sell for $ 5. The profit was $ 76

So:

3x + 5z = 76

To find the quantity of candy bars sold we must solve the system of equations:

x + z = 20\\\\3x + 5z = 76

Multiply the first equation by -5 and add it to the second equation

-5x -5z = -100

               +

3x + 5z = 76

--------------------------------

-2x = -24\\\\x = 12
