I think that this quesion is missing some background, that is that Ms. Donaldson earned 907.10
So the 34.55 were deduced from this number, and the remaining amount was:
907.10-34.55=872.65
After this, further 28% were deduced, which means that 100-28=72% were left.
And this is:72%*872.55= 628.236 (which we round to 628.24!)
The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
![[cos(x)][tan(-x)]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5Btan%28-x%29%5D)
is the same as
![[cos(x)][ -\frac{sin(x)}{cos(x)}]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5B%20-%5Cfrac%7Bsin%28x%29%7D%7Bcos%28x%29%7D%5D%20)
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.

Step-by-step explanation:
Veronica traveled at 85 miles for 6 days and 52 miles on the final day making the total number of days traveled 7 days
<em><u>Solution:</u></em>
Veronica traveled 562 miles to Venice, Florida
She drove 85 miles every day
Let "d" be the number of days she drove 85 miles per day
On the last day of her trip she only drove 52 miles
Therefore, we frame a equation as,
Total miles = 85 miles every day for "d" days + last day
Total miles = 85(d) + 52
Total miles = 85d + 52
562 = 85d + 52
85d = 562 - 52
85d = 510
d = 6
She traveled at 85 miles for 6 days and 52 miles on the final day making the total number of days traveled 7
