Answer:
380
Step-by-step explanation:
171:45=3,8
3,8*100=380
All percents are out of 100 so start with 15/100 and then simplify
3/20
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
Answer:
The original price is 337.50
Step-by-step explanation:
If we get 20% off, we still have to pay 100-20 =80%
Let x be the original price
x *80% = 270
.80x = 270
Divide each side by .80
.80x/.80 = 270/.80
x =337.50
The original price is 337.50
