35% of 347.250.35(347.25)121.54

Sale price

347.25-121.54$225.7

The sale price of the bat will be;

⇒ $225.71

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

                                          = $121.54

Thus, The sale price = $347.25 - $121.54

                                = $225.71

The prime factorisation is for the number is48.

What is prime factorisation?

Prime factorisation is a method to find the prime factors of a given number, say a composite number. These factors are nothing but the prime numbers. A prime number is a number which has only two factors, i.e. 1 and the number itself. For example, 2 is a prime number which has two factors, 2 × 1.
