Formula for markup
sales price = original price × ( 1 + rate )
So in this case it would be...
sp = $32 × ( 1 + .80 )
$32 × ( 1.80 )
sp = $57.60
formula for discount ( if you need it )
sales price = original price × ( 1 - rate )
Just remember that the rate is the percentage ( to convert to a percentage to a decimal just move the decimal two places to the left )
This is a problem in "binomial probability." Either the archer hits his target or he does not. This experiment is performed 5 times (so that n=5), and the probability that the archer will hit the target is 0.7 (so that p=0.7).
We need to find the binomial probability that x=3 when the possible outcomes are {0, 1, 2, 3, 4, 5}.
You could use a table of binomial probabilities to evaluate the following:
P(5, 0.7, 3).
Alternatively, you could use a TI-83 or TI-84 calculator and its built-in "binompdf( " function.
I evaluated binompdf(5,0.7,3) and obtained the result 0.309.
The increase is D: 50% because the 1 in the parentheses stands for the 20 that was already there, with the .5 being the amount that’s actually being increased. 0.5 translates to 50%, so the answer is D.
