There are 5 to use for the first bead; then after it is used, 4 for the second; 3 for the third; 2 for the fourth; and 1 for the fifth and last bead:
5*4*3*2*1 = 120.
Since we know that the sales tax is 20%, we must convert this percent to a decimal. Let's divide by 100 to make it a decimal:
Then we multiply the original price by the tax in decimal form:
So we know that the tax will total $2.80. Then we need to add this to the original price to find the total price of the meal:
Now we know the total price of Han's meal is $16.80.
