Felix is out shopping and finds a mountain bike
originally valued at $340.00. It is now on sale for 50% of
the original price.
What is the new cost of the item?

$189.00

Step-by-step explanation:

Using the total cost of the shoes before tax, but after the sale price and coupon were applied, $74.50, first add back the $20 discount from the coupon:

74.50 + 20.00 = 94.50

Then, add the new amount by itself to find the original price since the sale applied a 50% discount:

94.50 + 94.50 = $189.00

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 !

correct answer:

b.(19,-2)
