Answer:
933.
Step-by-step explanation:
a) if the number of miles is 'x', then
b) the price for 'The Ears-to-the-Wind' Car Rental is 100+0.11x;
the price for 'The Wheels Are Us' is: 128+0.08x;
using the two prices it is possible to make up the equation, then to solve it:
100+0.11x=128+0.08x; ⇒ 0.03x=28; ⇔ x=2800/3≈933.(3)=933 (miles).
c) the required number of miles, that would cause the rental fees of the two companies to be equal in one day, is 933.
