Denise’s cell phone plan is $29.95 per month plus $0.10 per minutes for every minute over 300 minutes of call time. denise's cell phone bill is $99.95. for how many minutes was she billed?

Step-by-step explanation:

$99.95 - $29.95 = $70.00

Minutes   :   Money

           1   :   $0.10

           ?   :   $70.00

Minutes   :   Money

           1   :   $0.10            

    ×700                            ×700

           ?   :   $70.00

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.
