5% of $89.95 is $4.4975. After subtracting this discount from the original price, the DVD player costs $85.4525. Rounded to the nearest cent, the final price is $85.45.
To find the cost of the $89.95 DVD player after a 5% discount, we need to first figure out how much 5% of $89.95 is. This is done by multiplying $89.95 by 0.05 (which is the decimal equivalent of 5%).
So, $89.95 * 0.05 = $4.4975. This is the amount of the discount.
Now, to find the final price after the discount, we subtract the discount from the original price. Therefore, $89.95 - $4.4975 = $85.4525.
However, we need to round this to the nearest cent, which makes it $85.45.

Both approaches yield the same result, so there are 87 dimes in $8.70.
To determine the number of dimes in $8.70, we can use two different approaches:
Approach 1: Division
1 dime = $0.10
To find the number of dimes, divide the total amount by the value of one dime:
Number of dimes = $8.70 / $0.10
Number of dimes = 87 dimes
Approach 2: Counting by 10 cent
$8.70 is equivalent to 870 cents (since 1 dollar = 100 cents).
Since each dime is worth 10 cents, we can find the number of dimes by dividing the total cents by 10:
Number of dimes = 870 cents / 10 cents
Number of dimes = 87 dimes
Both approaches yield the same result, so there are 87 dimes in $8.70.
