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.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
