Brenda is buying three birthday cards for $8.97. sales tax on the three cards is $0.63. what is the total cost?

From the information you provided, the answer would be $9.60.

The tax, $0.63, is added to the cost for all three cards, $8.97, thus making the final amount $9.60. $8.97 plus $0.63 equals $9.60.

Another way you could do it is dividing everything by 3, as she bought three cards. $8.97/3 is $2.99, thus making each card $2.99. $0.63/3 is $0.21, thus making the tax on each card $0.21.  Therefore, $2.99+$2.99+$2.99+$0.21+$0.21+$0.21 is $9.60.

Hope this helps!

step-by-step explanation:

4*4*4*4=256

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
