Answer:
x+5
Step-by-step explanation:
Since you don't know how much Joe weighs, you can express his weight as x. Then, you add on 5 because you have 5 more lbs than joe (which is x).
Using the 2nd row it traveled 120 miles in 3 hours
so 120/3 = 40 miles per hour
so distance (d) = 40h
7.5% is 3/40. The equation is y=15250(1-3/40)ˣ=15250(37/40)ˣ.
When x=8 this becomes $8173.42.
