Victoria works at the Apple Store. She is paid on commission. She receives 10% of her first
$2,000 in sales and 15% of the balance of her
sales. Last week she earned $1,800. What
was the total value of the products she sold?
$12.588.87
$15.125.33
$11,333.33
None of these
$13,445.87

9514 1404 393

  None of these

Step-by-step explanation:

A function describing Victoria's commission for total sales over $2000 could be ...

  f(s) = 0.10×2000 +0.15×(s -2000)

  f(x) = 0.15s -100 . . . . simplify

Then for a commission of 1800, her sales must be ...

  1800 = 0.15s -100

  1900 = 0.15s

  1900/0.15 = s = 12,666.67 . . . . matches none of the choices

For $12,588.87, the commission would be $1788.33

For $15125.33, the commission would be $2168.80

For $11,333.33, the commission would be $1600.00

For $13,445.87, the commission would be $1916.88

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

this is false ^.^ lol
