Suppose a book of william shakespeare's plays cost $19.75 if the tax is 8 percent what is the total cost of the book

Hello! We are looking for the total cost of the book. The tax rate is 8%. Let's add that to 100%. 100% represents the total price. 100 + 8 is 108%. Now, let's multiply. 19.75 * 108% (1.08) is 21.33. There. The total cost of the book is $21.33.

4.8%

Step-by-step explanation:

to do this create a ratio and cross-multiply

now that we have a our ratio, where x = the percent of poisonous trees, we can cross-multiply and solve to find its value

cross-multiplying leaves you with

now solve for x, dividing both sides of your equation by 1240

once you've divided, you should be left with

since this number is already out of 100, it is equivalent to your percent, so slap a percent sign on the end and you're done!
