Answer:
1. $8.
2. 48 counters.
Step-by-step explanation:
1. A pair of socks cost 20 - 2(6)
= $8.
2. let the number of counters in Box A and Box be be x.
Then the number of counters in Box B after the transfer is x + 1/2 x.
x + 1/2 x = 72

Answer:
Check the explanation
Step-by-step explanation:
let the money on bet is X.
probability of winning =18/38=9/19
probability of losing =(1-9/19)=10/19
expected outcome =
probability *return =(
Expected value of return after one bet is =(9/19*x)-(10/19*x)=-1x/19
it is negative which is obvious cause casinos are there to earn money.
a) Our best strategy in this case as probability of winning is near by 50 %, we should place a bet of 1 $ each,and when we lose one bet consecutively we should bet twice the amount..
Cause two consecutive losses on black has less probability.
c) In case we have to reach 30 $ we have to use the same strategy as above.

Answer:
Norman bought the shoes for $117.72
Step-by-step explanation:
In order to find the answer to this question, start by multiplying the cost by the markup.
$90 * 20% = $18.
Now we add the $18 to the original price.
$90 + $18 = $108
Now that we have the mark up price, we need to do the same using the tax.
$108 * 9% = $9.72
Finally, we add that to the previous total.
$108 + $9.72 = $117.72
