Answer: she spent three 1 dollar bills and and four 10 dollar bill.
Step-by-step explanation:
Let x represent the number of 1 dollar bills that she used.
Let y represent the number of 10 dollar bill that she used.
She used seven bills to buy a pair of shoes. This means that
x + y = 7
The amount that she spent on the pair of shoes is $43. This means that
x + 10y = 43 - - - - - - - - - - 1
Substituting x = 7 - y into equation 1, it becomes
7 - y + 10y = 43
- y + 10y = 43 - 7
9y = 36
y = 36/9 = 4
x = 7 - y = 7 - 4
x = 3
Answer: D
Step-by-step explanation:
.6(83.5)=50.1
83.5-50.1=$33.4
Answer:
$85
Step-by-step explanation:
For the insurance company mentioned in the question above, we have:
Outcome AA_cc AA
Profit (X) CC-15 CC-15-1000
p(x) 1-0.02=0.98 0.02
Therefore, we can deduce that the expected profit will be equivalent to:
E(X) = (CC-15)*0.98 +(CC-15-1000)*0.02 = 50
0.98CC-14.7+0.02CC-0.3-20 = 50
0.98CC+0.02CC = 50+14.7+0.3+20 = 85
CC = $85
Thus, the insurance company should charge $85 for the policy to obtain the estimated expected profit.
