Answer:
$60
Step-by-step explanation:
Let's say we need t $2 bills and v $5 bills.
We need 9 more $2 bills than $5 bills, so:
t = 9 + v
We also know that the amount of money in t $2 bills is 2 * t = 2t. The amount of money in v + 9 $5 bills is 5 * (v + 9) = 5v + 45. These amounts are equal:
5v + 45 = 2t
Plug v + 9 in for t in 5v = 2t + 18:
5v = 2t + 18
5v = 2 * (9 + v) + 18
5v = 18 + 2v + 18
3v = 36
v = 12
We have 12 $5 bills, so that total cost is 12 * 5 = $60.

GIVEN
The following values are given:
![\begin{gathered} \mu=10.3 \\ \sigma=3.8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cmu%3D10.3%20%5C%5C%20%5Csigma%3D3.8%20%5Cend%7Bgathered%7D)
SOLUTION
The z-score for the x values 9 and 14 can be calculated using the formula:
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
For x = 9:
![\begin{gathered} z=\frac{9-10.3}{3.8} \\ z=-0.34 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20z%3D%5Cfrac%7B9-10.3%7D%7B3.8%7D%20%5C%5C%20z%3D-0.34%20%5Cend%7Bgathered%7D)
For x = 14:
![\begin{gathered} z=\frac{14-10.3}{3.8} \\ z=0.97 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20z%3D%5Cfrac%7B14-10.3%7D%7B3.8%7D%20%5C%5C%20z%3D0.97%20%5Cend%7Bgathered%7D)
The probability can be calculated as follows:
![P(9\le x\le14)=Pr(-0.34The region that represents the solution is shown below:Therefore, the probability is given to be:[tex]P(9\le x\le14)=0.4671](https://tex.z-dn.net/?f=P%289%5Cle%20x%5Cle14%29%3DPr%28-0.34The%20region%20that%20represents%20the%20solution%20is%20shown%20below%3A%3Cp%3ETherefore%2C%20the%20probability%20is%20given%20to%20be%3A%3C%2Fp%3E%5Btex%5DP%289%5Cle%20x%5Cle14%29%3D0.4671)
The probability is 0.4671.
35-17= 18 so 18 divided by 4 is $4.50 each shirt
Sarah is 14
The twins are 12
The youngest (n) is 7
14+(12+12)+7=45
