Follow the steps to finish solving the equation -3x+18=7x
Svet_ta [14]

Answer:

x = 1.8

Sally buys a handbag. there was a discount of 30%. if sally paid, $17.50, what was the original price?
andrew11 [14]
The original price was $25. 

First, convert the 30% to a real mathematical number. For percents, this is always done by dividing the 30% by 100%, or 30% / 100% = 0.300.

Second, find out what 30% of $25 is. This is the amount of the sale discount. This is always found by mulitplying 0.300 by the item's cost $25, like this:

0.300 x $25 = $ 7.50.

So for this sale, you'll save $ 7.50 on this item.

This means, the cost of the item to you is

<span>$25 - $ 7.50 = $17.50.</span>
