the tuition cost for part - time students taking c credits at stonewall college is given by 300 + 100c dollars. (a) find the tuition cost for eight credits. (b) if the tuition cost is $1000, how many credits are taken?

Answer

Answer:

(a) 1100 (b) 7

Explanation:

Step1: Substitute C = 8

Substitute C = 8 into 300 + 100C. So we have 300+100×8 = 300 + 800 = 1100.

Step2: Set up equation

Set 300 + 100C = 1000.

Step3: Solve for C

First, subtract 300 from both sides: 100C=1000 - 300 = 700. Then divide both sides by 100, C = $\frac{700}{100}$ = 7.
