Let x be the number of tickets sold
Cost of x tickets = 32.5.x
Cost of convenience = 3.3.x
Process charges (for ONE ORDER, whatever the number of tickets) = $5.90
Hence:
$32.5(x) + $3.3(x) + $5.90 = $220.70
$35.8(x) = $220.90-$5.90
$35.8(x) = $214.8
And x = 214.8/35.8 = 6 tickets
28^2+45^2=53^2
Answer:
53 km
Answer: 12.50$
Explanation: 5.25$ (per pound) and he wants 3 pounds so we multiply 5.25x3 which equals 15.75 and then we subtract 3.25 (because of the coupon) which makes your final answer 12.50$
<span>Answers:
V = (15-2x)(8-2x)x
V = 120x -46x²+ 4x³
V' = 120 -92x + 12x²
0 = 120 -92x + 12x²
x = (92±52)/24
x = 6 or 5/3
Pick x = 5/3
Volume = (15-2*5/3)(8-2*5/3)*5/3
= 90.74 inÂł
To justify x = 5/3 is the max
V" = -92 + 24x
V"(5/3) = -92 + 24(5/3) <0 negative.
Volume V(5/3) is max because the function is
concave down with V"<0.</span>
I'm not sure what you mean by this, but if you mean rounding, I got an answer.
Say you're rounding 24 to 30.
24 is closer to 20 than 30.
But if you were rounding 25 to 30, 25 would be closer to 30, not 20.
I guess it's kind of confusing.
