Answer:

= $88.7429

Step-by-step explanation:

Regular price: $124.99

Total off: $124.99 x 20% + 15% = 43.7465%

Tax: $124.99 x 6% = 7.4994

So he should pay: 124.99 - 43.7465 +7.4994

$f(x)=10e^{\frac{x-1}{2}}$

substitute f(x) for y
$y=10e^{\frac{x-1}{2}}$

solve for x

$\frac{y}{10}=e^{\frac{x-1}{2}}$

$ln( \frac{y}{10}) = \frac{x-1}{2}$

$2ln( \frac{y}{10})=x-1$

$2ln( \frac{y}{10})+1 =x$

$2ln( \frac{y}{10})$ is esquivent to $2ln(y) - 2ln(10)$

$2ln(y)-2ln(10)+1=x$

Change x to y and y to x

$2ln(x)-2ln(10)+1=y$

Flip formula and substitute y for g(x)

$g(x)=2ln(x)-2ln(10)+1$

A parking garage charges a $2.50 daily fee plus an hourly rate of $4.00. If you have $12.50 to pay for parking, how long can you

Vesnalui [34]

Step-by-step explanation:

First we need to set up an equation so

12.50=4x+2.50

Simplify each side by subtracting the initial fee of 2.50

10=4x

divide by 4 to isolate x

2.5=x

You can park for 2.5 hours with your budget

Company earns S dollars by selling y items per week. According to the equation S(y)=−2y^2+60y+10, how many items does company ne

sp2606 [1]

Answer:

$Max = 15$

Step-by-step explanation:

Given

$s(y) = -2y^2 + 60y + 10$

Required

Determine number of items that gives maximum earnings;

The general form of a quadratic equation is:

$s(y) = ay^2 + by + c$

And the maximum is calculated as:

$Max = \frac{-b}{2a}$ If a<0

Comparing $s(y) = ay^2 + by + c$ to $s(y) = -2y^2 + 60y + 10$

We have that:

$a = -2$ $b = 60$ $c = 10$

Substitute these values to

$Max = \frac{-b}{2a}$

$Max = \frac{-60}{2 * -2}$

$Max = \frac{-60}{-4}$

$Max = 15$

<em>The number of item that maximizes the function is when y = 15</em>
