Question 37666
Let x be the number of miles driven.
Then change the English into algebra giving us the equation
17.99 + .18x = 18.95 + .16x
Now multiply everything by 100 to clear the decimals
1799 + 18x = 1895 + 16x
Now subtract 16x and 1799 from both sides
1799 + 2x = 1895
2x = 96
so that x = 48 miles
