Answer: Her new salary would be $25.30. She would be making $69 more than her usual 30 hours per week.
Step-by-step explanation: Do $23 times 0.10, because the 10% is being turned into a decimal. Now add the product of that, $2.30, to the original $23, which is $25.30. This will be her new salary. Multiply $25.30 by 30 to get the amount that she would make with her usual amount of hours per week. Then, multiply $23 by 30 to get the amount of money that she would make for that. What you should end up with is 759 - 690, which equals 69. So she would make $69 more.
