Answer:
1. 16/27 (cannot be reduced any further [in simplest form])
2. 2/3 (96/144 reduced into simplest form)
<span>a.
</span>Let m = be the number of miles driven
Cost of NYC rentals: 525 + 0.21m
Cost of Metro Trucks: 585 + 0.13m
<span>b.
</span>525 + 0.21m = 850
0.21m = 325
M = 1,548 miles
<span>c.
</span>Initial cost for NYC rentals = $525
Initial cost for Metro Trucks = $585
<span>d.
</span>NYC rentals: 525 + 0.21 (500) = $630
Metro Trucks rentals: 585 + 0.13 (500) = $650
<span>e.
</span>525 + 0.21m = 585 + 0.13m
0.21m – 0.13m = 585 – 525
0.08m = 60
m = 750 miles
