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.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
