Question

A computer that originally cost $850 is on sale for 15% Off. What is sale price of the computer? Help Please <3 Thanks!

Answer 1

Hello there! So what we know is that the cost of the computer is 15% off. However, you still have to pay 85% of the original price, because 100 - 15 is 85. The original price is $850. We can multiply that price by 85% to get the new price. 850 * 85% (0.85) is 722.5. There. The sale price of the computer is $722.50.

Answer 2

Percent means per 100
think cent as in 100 pennies in a dollar

To convert from percent to decimal, we divide by 100 or move the decimal over 2 spots, so,
15% = 15/100 = 0.15

Now multiply 0.15 by 850 to find the discount saved
0.15*850 = 127.50
So you'll save $127.50

The final price is therefore: 850-127.50 = 722.50

A shortcut is to multiply 850 by 0.85 
850*0.85 = 722.50
We get the same answer
The 0.85 comes from the fact that if you get 15% off, then you pay 85% of the original price

Answer: $722.50
