Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a c

opy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences.

Answer:

Step-by-step explanation:

Tess is wrong while Dan is correct. This is because tax is calculated after discount.

Finding the correct amount they are supposed to pay:

Price after discount = 85/100 x 24.5 = 20.825

Price after tax = 110/100 x 20.825 = 22.90

Since they have $24 each, it means they can purchase the book

AlekseyPX

Answer:

48 cubes

Step-by-step explanation:

step 1

Find the volume of one 1/2 unit cube

The volume of the cube is given by

V=b^3

where

b is the length side of the cube

we have

b=\frac{1}{2}\ units

substitute

V=(\frac{1}{2})^3

V=\frac{1}{8}\ units^3

step 2

Divide the volume of the prism by the volume of one cube

6:\frac{1}{8}=6(8)=48\ cubes
