Answer:
To convert 7.55 dollars into dimes and quarters, we need to make use of the fact that there are 10 dimes in a dollar and 4 quarters in a dollar. Here's how to do it:
Explanation:
1. First, convert the dollar amount into cents: 7.55 dollars x 100 cents/dollar = 755 cents.
2. Next, use long division to find how many quarters are in 755 cents: 755 ÷ 25 = 30 with a remainder of 5.
3. The quotient of 30 tells us that we can use 30 quarters, which equals $7.50.
4. The remainder of 5 cents is less than a quarter, so we cannot use another quarter. Instead, we can use 1 dime, which is worth 10 cents.
Therefore, 7.55 dollars is equivalent to 30 quarters and 1 dime.
