15 candy bars are solddd

Step-by-step explanation:

I believe the answer is $3.50

Step-by-step explanation:

1. You can see that 2 candy bars (x axis) sold result in $7 being spent (y axis).

2. To get how much the band makes for selling 1 candy bar, you divide the $7 by two.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
