For question 3, list down the multiples of 3 and 4. Since the question says that she is between 20 and 30 years old now, cancel the numbers that are below 20. Next, do note that the difference between her age now and her age next year is 1 year. Hence, find the numbers in the multiples of 3 and 4 that have a difference of 1. Lastly, check that her age now and next year is between 20 and 30 years old.

a)
4+3=7
$3.60×3=$10.80
$111.60-$10.80=$100.80
$100.80÷7=$14.40
b)
$14.40+$3.60=$18.00
