Work hours per day =
Therefore, Sara works for 5 hours and 15 minutes per day

Answer:
$719.95
Step-by-step explanation:
If the computer is originally $849 and you receive a 20% discount. This means you'll pay 80% of the price since 100-20=80.
To find this price, 80% as 0.8 is multiplied with the price. 0.8*849 = $679.20
This is the sale price.
When you pay you will pay 6% tax or 0.06 of the price. Find this by multiplying $679.20 by 1.06.
679.20(1.06) = 719.95
Answer: Choice D
9, 30, 93, 282, 849
============================================================
Explanation:
The notation tells us that the first term is 9
The notation says that we multiply the (n-1)st term by 3, then add on 3 to get the nth term
So if we wanted the second term for instance, then we'd say
If we want the third term, then,
and so on.
The terms so far are: 9, 30, 93
You should find the fourth and fifth terms are 282 and 849 respectively if you keep this pattern going.
Therefore, the answer is choice D
