Question

Solve:

The total cost (C) in dollars for building a house of x square feet is given
by the function C(x) = 50,000 + 155x.
If the total cost was $283,275.00, how many square feet was the house?

Answer 1

1505 square feet.

Explanation:

okay so what you do is:

283,275.00-50,000; because 50000 is one section of 283,275 and we are trying to find what 155x equals.

283,275- 50,000= 233275

233275/155= 1505; you do this next because you found out that 283,275- 50,000= 233275, so now you have to divide 233275 by 155 because you have to find out what x is. and your answer is 1505
