An electronics store is having a sale on new sound systems. if a $625.00 model is on sale for 35% off, what is the actual cost of the sound system?

The actual cost of the sound system is $961.54.

Step-by-step explanation:

This question can be solved using a rule of three.

$625.00 model is on sale for 35% off

This means that $625 is 100-35 = 65% of the original price. How much is 100%?

x - 1

625 - 0.65

0.65x = 625

x = 625/0.65

x = $961.54.

The actual cost of the sound system is $961.54.

the answer is 15% decrease

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%
