The last one is a proportion!
Answer:
$504
Step-by-step explanation:
Step one:
given data
A shirt that cost $420
we are told that the shirt was on a discount sale of 20%, so when the discount is over the price will return to $420, we are then told that the shirt was marked up 20%.
Step two:
Hence the new cost is
=20/100*420+ 420
=0.2*420+420
=84+420
=$504
Answer:
6/20 = 3/10
Step-by-step explanation:
Her brother gets the first treat. There are 2 grape treats out of 3+2 = 5 total; this is a probability of 2/5.
Maggie gets the second treat. There will still be 3 cherry treats left, but only 5-1 = 4 treats remaining; this is a probability of 3/4.
Together this gives us 2/5(3/4) = (2*3)/(5*4) = 6/20 = 3/10
subtract 3 from 23 and u will get 20 then divide 2 by 2 and 2 by 20
x= 10
