Answer:

Step-by-step explanation:

See the attachment for derivation of the equation.

y = -(6/7)x + 20 6/7

The y-intercept of the equation is 20 6/7, which means there is 20 6/7 hours of setup time required.  When Anna arrives, she has not yet done any setup, so she would not have done any work yet.

In any event, the graph does not tell us how much time Anna really worked.  Did Anna spend 6 or 9 hours on the setup?  We don't know.

A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An it
lyudmila [28]

Answer:

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

Step-by-step explanation:

For the $200, the restocking fee is $12, so the ratio of the restocking fee to the price of the item is 12/200.

For the $150, the restocking fee is $9, so the ratio of the restocking fee to the price of the item is 9/150.

Now we find out if the ratios 12/200 and 9/150 are equal.

12/200 = 3/50

9/150 = 3/50

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.
