Answer:
40
Step-by-step explanation:
so next year her money would be 6% more so:
5000 + (0.6 * 5000) = (1.06) * 5000
So each year she'll have : (1.06)*(last year's money)
So we can say after n years she will have :
((1.06)^n) * 5000
So:
5000((1.06)^n)=50000
n is 39.5
So around 40
Answer:
Total amount paid to staff = $250
Step-by-step explanation:
Given:
Weekly payment = $200
Commission = 5% on sales
Amount of jewelry = $1,000
Find:

Total amount paid to staff = $200 + $50
Total amount paid to staff = $250
Answer:
Both are correct.
Step-by-step explanation:
In the point (4,-2) and (4,-7), the x-coordinates are same. So, the distance between these points is the absolute difference between the y-coordinates of these points.

So, Laura is correct.
In the point (2,3) and (-9,3), the y-coordinates are same. So, the distance between these points is the absolute difference between the x-coordinates of these points.

So, Ryan is correct.
Hence, both are correct.
