Dwain is out shopping and finds a $110.00 scooter that is
marked down by 50%.
BILLEDER
How much will be taken off of the price in dollars?
What is the new cost of the item?

$55

Step-by-step explanation:

1) since we are taking 50% of the price of lets find 50% of 110

so 0.50*110=55

50% of 110 is 55 hence we can subtract 55 from 110(since its getting marked down)

110-55=55

$55 is the new price

Hope this helps!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
