If cos(70) = 0.342
the cosine of the alternative angle of 70° will also give the same value
angle measure = 360 - 70 = 240°
cos (240) will also be 0.342
Answer:
n ≤ 6
Step-by-step explanation:
If Tom needs to schedule employees to staff the deli department for no more than 260, the number of hours worked (W) is less than or equal 260 (W ≤ 260).
Assuming that Tom's only part-time employee is assigned to work 20 hours at the deli department, the total number of hours worked is given by:
![W = 20 +40n](https://tex.z-dn.net/?f=W%20%3D%2020%20%2B40n)
The inequality that determines the number of full-time employees (n) that Tom may schedule is:
![260 \geq 20 +40n\\240 \geq 40n\\n \leq \frac{240}{40} \\n \leq 6](https://tex.z-dn.net/?f=260%20%5Cgeq%2020%20%2B40n%5C%5C240%20%5Cgeq%2040n%5C%5Cn%20%5Cleq%20%5Cfrac%7B240%7D%7B40%7D%20%5C%5Cn%20%5Cleq%206)

Answer:
$91.76
Step-by-step explanation:
Interest the first month was ...
I = Prt
I = $15000(0.0387)(1/12) = $48.375 ≈ $48.38
Interest in the second month was ...
I = $15000(0.0347)(1/12) = $43.375 ≈ $43.38
So the total interest amount is ...
$48.38 +43.38 = $91.76
Marcella earned $91.76 in two months.

<em>Comment on rounding</em>
We have assumed that Marcella's account statement will report the interest rounded to 2 decimal places (cents). Hence she obtains the benefit from rounding for both months.
If there is no statement, so that rounding is not required until the end of the second month, then she may not have that extra penny in her account.
