(this question is kinda wierd. i do not know if i am correct, because mine is not exactly a system of inequalities, but if you really need an answer, you can try this one.)
Answer:
$8/mile
Step-by-step explanation:
Total distance walked was 2 1/4 mi + 5 1/2 mi = 7 3/4 mi. Please note: you must use the " / " symbol to indicate division; "2 1 4" is unclear.
$62
Unit rate = $ per mile = --------------- = $8/mile
7 3/4 mi
6 divided by 1/3 equals 6 times 3
6*3 = 18
