Answer

a) 350 dollars b) 260 dollars c) It decreases due to the denominator increasing

Work Step by Step

a) As we've been told the value for x (number of fax machines manufactured) is 100, you simply substitute 100 in for every x. C=$\frac{250(100) + 10,000}{(100)}$ b) New value for x is 1000, you simply substitute 1000 in for every x. C=$\frac{250(1000) + 10,000}{(1000)}$ c) As you increase x, you increase the numerator but you also increase the denominator. Because you increase the denominator, it means you divide by a bigger number. The larger the number you divide by, the smaller the result will be.
