Answer:
D
Step-by-step explanation:
national cell= 0.15t+5
world wireless= .19t
its asking for when world wireless is cheaper so
0.19t< 0.15t +5; t<125
3.3 miles should be the answer
10 = 2.40 + .2x - take 2.4 from both sides
7.6 = .2x - take 2 from 7.6 for the tip
5.6 = .2x - divide both sides by .2
28 = x
this means that you can pay the taxi drives an additional 28 times with the .20 cents fee and still have 2 dollars left over
now multiply 28 by .1 miles which is 2.8 miles
add 2.8 miles to .5 miles which equals 3.3 miles
