Answer:
the answer is 21
Step-by-step explanation:
-16t^2+400=0
16t^2=400
take square root on both sides.
4t=20
t=20/4
t=5
First we have to find how much Kyle earned taking to consideration only 38h at work
So 38*14$=532$
Now, to find commission bonus we have to 1200-532=668
Finally, we can find what dollar amount of car Kyle must sell.
We know that 668 is 8% of that number. We can use proportion and cross multiplying, so:
8% ----------- 668
100% --------x
$ - its the result.
It would be 0.81 because she got 81/100 right. Hope this helpz..
