How do you find a Mark-up or Mark-Down for retail prices? For example;Original price; $279.99, Mark-down: 75%. And can someone please show how its done? Thanks. :)

Answers

You take $279.99 x 75% then subtract what you you get from $279.99. This is is markdowns so for a mark up you add instead of subtracting.

Mark Up: Store pays $40 for shoes and sells to me for $75.calculate the markup in absolute terms 75 – 40 = 35. Narkup rate $40 (x)(40) so markup over the original price is 35 ÷ 40 = x = 0.875. It's a percentage so you need to use the decimal in the correct percentage which is 87.5%

Mark down: Original $425 marked down to $318.75. 425-318.75=106.25 ($106.25) is (some percent) of ($425) so 106.25 = (x)(425) and x = 106.25 ÷ 425 = 0.25. Use decimal to % form which is 25%

What is1\7 the speed of a cheetah?

Answers

1/7 the speed of a cheetah is 10 mph because an average cheetah can run 70 miles per hour. This means time to do some division. Envision the denominator of 1/7 (7) as 70 and then the numerator (1) should be 10. Divide 70 by 7 should be 10. Hope this helps.

Since the speed of the cheata is93 k then that 1/7 of that is 13and 2/7. Hope this helped :)
