Piecewise Word

Suppose a carpet store sells carpet for $10 per square yard for the 100 sq yards purchased, and then lowers the price to $7 per square yard after the first 100 yards have been purchased.

How much does it cost for 170 square yards?

• $490

• $1000

• $1,490

• $1,680

Determine the input, x, and the output, f(x), in the following piecewise function scenario. If you earned up to $165,000 a country taxes you at a rate of 7.6%. If you earned over $165,000 and up to $600,000, you paid a fixed amount of $8,124. Write a piecewise function to represent the taxes paid in dollars between $0 and $600,000.

• The input, x, represents the taxes paid in dollars.

  The output, f(x), represents the person's salary

• The input, x, represents the person's salary.

  The output, f(x), represents the taxes paid in dollars.
