Twice (2 x ) a number (n), subtracted (-) from 36, is less than (<) 15 more than (+) one-third (1/3) the number (n).
36 - 2n < 15 + 1/3n Subtract 15 from both sides
21 - 2n < 1/3n Add 2n to both sides
21 < 7/3n Multiply both sides by 3/7 to cancel out the fraction
63/7 < n Simplify the fraction
9 < n Switch the sides to make it easier to read
n > 9
The possible values for the number are anything over 9.
Last year = $5.00
Increase = 5% of $5
Increase = 0.05 x 5
Increase = $0.25
This year = $5 + $0.25 = $5.25
1/2 mile = $5.25
1 1/2 miles = $5.25 x 3
1 1/2 miles = $15.75
