graph%28300%2C300%2C-5%2C70%2C-5%2C100%2C-0.85x%2B100%29
I make a graph with made up miles but the slope is real. This allows me to visualize the problem.
Every 10 minutes, she has 8.5 fewer miles to go. That is a slope of -0.85
She has 48 miles left after 50 minutes. In 16 minutes, she is going to drive 16*0.85=13.60 miles
She will have 48-13.6=34.4 miles

Add 6% to 100%, get 106%

NEW SALARY = 106% OF OLD SALARY

%28matrix%282%2C1%2CNEW%2CSALARY%29%29%27%27=%27%27%27106%25%27%27%27%2A%27%27%28matrix%282%2C1%2COLD%2CSALARY%29%29

19610%27%27=%27%271.06x

Divide both sides by 1.06

19610%2F1.06%27%27=%27%27x

18500%27%27=%27%27x

%27%2418500%27%27%27=%27%27x
