(40-10)/7
The maximum amount of money she wants to spend is $40
Her adult ticket costs $10
She will pay for the children’s tickets with the remaining money
Each child’s ticket costs $7
To find the number of children she can take we need to use this expression (40-10)/7
Mrs Herñàndez can take 4 children
Answer:
<h2>Here</h2>
The numbers less than 50 (A) = 4
Total numbers (S) = 14
Probability students below 50 = 4÷14
Step-by-step explanation:
That is the correct answer of it.
We can create two equations here:
(1) Volume = area of square * height of box
85.75 = s^2 h
(2) Cost = 3 * area of square + 1.5 * area of side box
C = 3 s^2 + 1.5 s h
From (1), we get:
h = 85.75 / s^2
Combining this with (2):
C = 3 s^2 + 1.5 s (85.75 / s^2)
C = 3 s^2 + 128.625 s-
Taking the 1st derivative and equating dC/ds =
0:
dC/ds = 6s – 128.625 / s^2 = 0
Multiply all by s^2:
6s^3 – 128.625 = 0
6s^3 = 128.625
s = 2.78 cm
So h is:
h = 85.75 / s^2 = 85.75 / (2.78)^2
h = 11.10 cm
So the dimensions are 2.78 cm x 2.78 cm x 11.10 cm
The total cost now is:
C = 3 (2.78)^2 + 1.5 (2.78) (11.10)
C = $69.47
The answer is $3990 heres why
First you need to find out what is the total you paied for the shares
$18.12x200= $3624
Then you need to add the flat fee to the spending chost
$3624+$30= $3654
Now you re-mulitply the chost per stock to the tootle #'s of stock you sold
$21x200= $4200
Then you need to find out what how much you need to pay the stock broker
$4200x.05= $210
Then once you find out how much you need to pay him subtract that amount to the total money earned from selling your stocks
$4200-$210= $3990
Then if you want to also find out your profit just subtract the total amount you payed for the stock and subtract it from the total amount you gained from the stock.
$3990- $3654= $336 Profit
It’s the third one for this question
