Christen takes classes at both west side community college and pinewood community college. At west side, class fees are $98 per credit hour, and at pinewood, class fees are $115 per credit hour. Christen is taking a combined total of 12 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.

step-by-step explanation:

your answer is -9

step-by-step explanation:

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.

the answer is a and d
