It rounded to the nearest dime what is the greatest amount of money that rounds to $105.40

$105.44.

Step-by-step explanation:

We are asked to find the the greatest amount of money that rounds to $105.40, rounded  to the nearest dime.

We know that when the next digit to rounded digit is 0, 1, 2, 3, 4; then we keep the same digit.

When the next digit to rounded digit is 5 or more than 5; then we round up our answer by one digit.

We know that 1 dime equals $0.10.

Since our answer in rounded to nearest dime, so the hundredths digit will be less than 5.

Therefore, the greatest amount of money would be $105.44.

$25

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
