This is the process I would use:
Maddy's = 2x 2x+x=15

Average mean salary 
Step-by-step explanation:
We have been given year and respective salaries in each year.
1960 $4,995
1970 $8,626
1980 $15,970
1990 $31,367

Answer:
3 Hours
Step-by-step explanation:
Plumber A.
Initial fee: $45
Per Hour: $60
Plumber B.
Full rate: $225
To determine the number of hours it will take for both plumbers to charge the same amount you have to start with $45.
Then add 60$ every hour.
$45 + $60 = $105
$105 + $60 = $165
$165 + $60 = $225
Therefore, it takes 3 hours for them to charge the same rate.
