Answer: Her new salary would be $2.48
Explanation:
1. take 10% of the current salary to figure how much the raise is.
2.25 x 0.1 = 0.225
2. round that number to the nearest hundredth (money only goes to the hundredths)
0.225 --> 0.23
3. now add that number back to the original salary to find the new salary
0.23 + 2.25 = 2.48
Final answer: the new salary is $2.48
