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.
