Edgar Anderson earns $200 a week plus a 15% commission on all sales over $1,000. If Mr. Anderson's sales for one week are $2,500

nignag [31]

<span>Find the gross pay of Mr. Anderson in a week.
He earns 200 dollars a week + 15% commission on over 1000 dollars sales.
In a week he earned 2500 dollars.
=> Pls, take note, that he can only get a 15% commission for over 1000 dollars sales he get.
=> 2 500 dollars – 1 000 dollars
=> 1 500 dollars, now in 1500 dollars get the 15% commission
=> 1 500 x .15
=> 225 + 200 (his original earnings)
=> 425 dollars.</span><span>

Notice the graph, the domain is just the horizontal area "used up" over the x-axis, so, the graph goees from $\bf -\cfrac{5x}{2}\quad to\quad \cfrac{5x}{2}\implies domain\implies \left[-\cfrac{5x}{2}\ ,\ \cfrac{5x}{2}\right]$

the range is just, the vertical area "used up" over the y-axis, so, the graph goes to 2 and down to -2, thus $\bf range\implies [2\ ,\ -2]$

Use the formula for continuous compounding to compute the balance in the account after 1,5, and 20 years. Also, find the APY for

densk [106]

Answer:

After 1 year: $7,256.59

After 5 years: $8,380.52

After 20 years: $14,381.03

APY = 3.66%

Step-by-step explanation:

If you deposit $7000 with an interest of 3.6%, after 1 year using continuous compounding, you will have

$7000e^{0.036}=7,256.59$

After 5 years you will have

$7000e^{5(0.036)}=8,380.52$

After 20 years

$7000e^{20(0.036)}=14,381.03$

To find the APY for the account, we have to compute the interest earned in one year.

We can do it by cross multiplying or by finding a number x such that

$7000(1+\frac{x}{100})=7,256.59$

Operating on this equation we obtain

x = 0.0366 or 3.66%
