A suit is on sale for 281.20 , which is 38% of the regular price.

To find the regular price, we can use the formula:

regular price = sale price / discount rate

where the discount rate is the percentage expressed as a decimal (e.g. 38% = 0.38).

Substituting the given values, we get:

regular price = 281.20 / 0.38 = 739.47

Therefore, the regular price of the suit is $739.47.
