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 $1100, how many credits are taken?

Answer

Explanation:

Step1: Substitute C = 8

Substitute C = 8 into the formula 300 + 100C. $300+100\times8$

Step2: Calculate the value

$300 + 800=1100$

Step3: Solve for C when cost is 1100

Set 300 + 100C = 1100. $300+100C = 1100$ Subtract 300 from both sides: $100C=1100 - 300$ $100C = 800$ Divide both sides by 100: $C=\frac{800}{100}=8$

Answer:

(a) $1100 (b) 8
