How much did alex pay for the books? Write your answer up to two decimal places. Alex paid $ for the books.

Answer 1

For starters, we need to calculate the original total price (the price he wouldve had to pay if there was no discount). If he bought 6 books, and every book costs $8, then he wouldve had to pay 6*8 dollars or 48 dollars.

Now, he got 20% off of the price, meaning they took 20% of the total price and subtracted that from the total price.

Lets calculate 20% (which can also be written as 20/100, or 2/10):

48 * (2/10)
48*2 / 10
96/10 = 9.6

This is what the cashier took off the total price.

48.00 - 9.60 = 38.40

So he spent $38.40 in total on books.
