BRAINLIEST!! How many times will the digit '3' appear if we write all whole numbers from 1 to 9999?

4000

Step-by-step explanation:

The amount of times 3 appears from 1-100 is 20 as it appears 10 times as the ones digit and 10 times as the three in the thirties.

Additionally, in the 300s, there are 100 more 3s as each number begins with a three.

So, there are 200+100=300 3s from 1-1000

this means that there are 3000 3s from 1-9999 plus an additional 1000 3s in the 3000s.

In total that is 4000 3s.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
