Answer: 45 ft
Step-by-step explanation: 3 times 15 equals 45
Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.
Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63
So 5 red cars
1/3 of all cars are red
therefor
5=1/3 of all cars
'of' means multply
5=1/3 times all cars
multiply both sides by 3
15=all cars
how many are left
basically how many are NOT red
15=all
red=5
all-red=others
15-5=others=10
10 cars are left
