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

$-5x -5z = -100$

$3x + 5z = 76$

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

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

lakkis [162]

Answer:

x + y = 5

3x + 3y = 15

Step-by-step explanation:

let x represent apple and y represent orange

Hence x + y = 5

and 3x + 3y = 15

Solving both equations simutaneously

From first equation, x = 5-y

Substitute x=5-y into the second equation

3(5-y)+3y = 15

y= 0

x = 5-0 = 5
