Answer

karen takes classes at both westside community college and pinewood community college. at westside, class fees are $98 per credit hour, and at pinewood, class fees are $115 per credit hour. karen is taking a combined total of 16 credit hours at the two schools. suppose that she is taking w credit hours at westside. write an expression for the combined total dollar amount she paid for her class fees.

y = 98w + 115(16 - w)

Step-by-step explanation:

Let y = total amount paid

Let w = credit hours in Westside

Let 98w = Westside Fee

Let 115(16-w) = Pinewood

Then we get:

y = 98w + 115(16-w)

Now how did get 16 - w?

We got that by analyzing the problem. We have a total of 16 credit hours and w represents the number of hours at Westside. So we take the total of 16 hours and deduct it to the number of hours that Karen took in Westside.

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.

i suppose it should be (y=2x-5)
