Answer:
The probability that this occurs is 25%, as 3/6 (chance to roll an odd number) multiplied by 1/2 (chance to flip a head) is .25.
Step-by-step explanation:
The √125 can be factored out to 25 and 5 then 25 can be factored out to 5 and 5. Then you pair up the numbers, you have a pair of 5's and a 5 left over. So the pair of 5's goes inside the radical as √5 and on the outside of the radical you have 5×3. So 3√125≈15√5.

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
20% × 6 = (20/100) × 6 = 1.2
