Chapter 4.8, Problem 29E

To determine

What is the college graduate’s new salary?

  $\text{A \$0}\text{.90}x\text{ B \$0}\text{.99}x\text{ C \$}x\text{ D \$1}\text{.01}x\text{ E \$1}\text{.11}x$

Answer to Problem 29E

  $\text{B \$0}\text{.99}x$

Explanation of Solution

Given information: SAT/ACT Practice: A college graduate goes to work for $x per week. After several months, the company falls on hard times and gives all employees a 10% pay cut. A few months later, business picks up and the company gives all employees a 10% raise.

Calculation:

If x = Weekly Salary

Falling on hard times is: $x-0.10x=0.9x$

Getting a 10% raise is:

  $0.9x+0.10\left(0.9x\right)=0.99x$

Thus,

This matches: $\text{B \$0}\text{.99}x$
