Answer:
$1954
Step-by-step explanation:
Given the profit function expressed as;
y=-3x^2 + 197x –
1279
The profit is at maximum when dy/dx = 0
dy/dx = -6x + 197
0 = -6x+197
6x = 197
x = 197/6
x = 32.83
substitute 32.83 into the modeled function
y=-3x^2 + 197x –
1279
y -3(32.83)²+197(32.83) - 1279
y = -3(1,078.03)+6,467.51 - 1279
y = -3,234.09+6,467.51-1279
y = 1,954.42
hence the maximum amount of profit the company can make, to the nearest dollar is $1954
In this question, the interest rate is 0.02% and you need to have $9.99 interest to cover the fee. To find the bank account needed, you need to divide the target interest value with the interest rate. The calculation would be:
interest = bank account * interest rate
$9.99 = bank account * 0.02%
bank account = $9.99/ 0.02% (don't forget the % mean 1/100)
bank account = $49,950
<span>3x+2 (5x+4)=47
47- 4 = 43
43/5= 8.6
8.6-2= 6.6
6.6/3= 2.2
2.2 <-- answer</span>
