A suit is on sale for 71% off. The sale price is $278.40.
What is the regular price?

$476.06

Step-by-step explanation:

According to the word problem, the suit is on sale for 71% off.

This means the original price was decreased by 71%.

To find the original price, we increase the sale price (278.40) by 71%.

To do this, we simply multiply 278.40 by the decimal form of 71.

To find the decimal form of 71, divide 71 by 100.

71 / 100 = 0.71

Now, we multiply.

278.40 x 0.71 = 197.664

Further, we add the product of this equation to the sale price.

278.40 + 197.664 = 476.064

476.064 rounded to the nearest hundredth is 476.06

Therefore, the regular price is $476.06.
