Answer:

Step-by-step explanation:
Number of times she climbed 5-mile mountain trail = x
Number of times she climbed 10-mile trail = y
total distance of the 5-mile mountain trail will be = 5*x =5x
total distance of the 10-mile mountain trail will be = 10*y = 10y
equation that can be used to find the number of times she hiked each trail is therefore
5x + 10y = 90
Original Income = 15,000
New income = 20,000
The percentage Increase in the income can be calculated as:

%
The change in income = 20000 - 15000 = 5000
Using the values, we get:

%
=

%
This means, Pats income increased by 33.33% in a period of ten years
To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.
65-50=15
15/60=0.25
0.25 times 100 =25%
