An item is regularly priced at $75.00. It is now priced at a discount of 45 off the regular price.

See below.

Step-by-step explanation:

Your question is unclear, and there is no question asked.

Is the discount $45 off the regular price or 45% off the regular price? Is the question "What is the discounted price?"

I'll answer it both ways.

If the discount is $45, then the discounted price is

$75.00 - $45.00 = $30.00

If the discount is 45%, then we first find 45% of $75.

45% of $75 = 0.45 * $75 = $33.75

The 45% discount is a discount of $33.75.

Now we subtract the discount from the original price.

$75.00 - $33.75 = $41.25

The price after the discount is $30.00 or $41.25 depending on what the question is.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
