A TV that usually sells for $192.74 is on sale for 25% off. If sales tax on the TV is 5%, what is the price of the TV, including tax?

Step-by-step explanation:

If you are saving 25%, you are still paying 75%, right?  So the cost of the TV with a discount of 25% is 192.74(.75) which is $144.56

That's the cost of the TV on sale.  Now we need to find the sales tax amount, if the sales tax is .05 as a decimal.  We are paying $144.56 for the TV, which is 100% of the cost.  On top of that, we are paying another 5%.  So altogether, for the TV, we are paying 105% of the TV.  Therefore,

144.56(1.05) = $151.79

step-by-step explanation:

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 !
