last years computer models are discounted 20% what is the original price to the nearest dollar of a computer that now costs 1,480

$1850.

Step-by-step explanation:

If the original price was $ x, then

x - 0.20x  = 1480

0.8x = 1480

x = 1480 / 0.8

x = 1850 dollars.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
