Given
Shape: Cone
--- rate of the radius
--- rate of the height
Required
Determine the rate of change of the cone volume
The volume of a cone is:
Differentiate with respect to time (t)
Substitute values for the known variables
The volume is decreasing at the rate of 1.396 cubic inches per minute
A jacket is on sale of 20%. Now, the sale price of the said jacket is 50 dollars that is already deducted with the 20% discount.
=> 100% - 20% = 80%, thus 50 dollars is the 80% of the original price.
=> 50 dollars / 8 = 6.25 dollars is the 10% of the price.
=> 6.25 dollars * 10 = 62.5 dollars is the original price of the jacket.
Mult. $7.25 by 4 times 4 (4 PIZZAS per week, for 4 weeks):
$7.25(4)(4) = $116
Fine dining: 2($85) = $170
So, the fine dining costs more!
