Question

Web Consultants, Inc., pays Alice Rose an annual salary of $48,000, Alice's boss informs her that she will receive a $6,400 raise. What percent of Alice old salary is the $6,400 raise? ( Round to the nearest tenth percent.)​

Answer 1

Answer: p = 0.13

Step-by-step explanation: Alice will receive, after the raise:

$48,000 + $6,400 = $54,400

When we add a percentage of raise to a number, we write:

x ( 1 + r )

where

x is the number we want to raise

r is the ratio we want to raise

So, for Alice's salary:

48,000(1 + r) = 54,400

1 + r = 1.13

r = 0.13

The $6,400 raise is 0.13, in nearest tenth percent "form" or 13% Alice's old salary percent.
