What is the better buy a refrigerator originally mark $360 with a 20% discount or the same refrigerator marked $288 with no discount

they are both the same price of $288.

Step-by-step explanation:

360•.2=72

360-72= 288

20% off of $360 is sale price of $288.00

Either way is same price.  

If it is the same refrigerator model and they are running a sale, I would say the sale model is smarter purchase considering the one not on sale that was already at a discounted price would have to be marked lower for a reason, like it was previously purchased & returned, a floor model, missing an accessory, refurbished, out of box item, or even slightly damaged perhaps (dent, crack, chip, etc).

Step-by-step explanation:

20% of $360.00 =

0.2 * 360 = 72.0

360 -72 = $288.00

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
