Answer: location b
Step-by-step explanation:
The rent of the house in location a per passerby is obtained as follows
(rent per passerby) = (total rent in location a)/(number of passerby)
= ($1,000)/140
= $7.14 (for location a)
Similarly, the rent per passerby in location b is given by
(rent per passerby) = (total rent in location b)/(number of passerby)
= ($1,500)/230
= $6.52 (for location b)
Hence, the rate of rent per passerby in location a is $7.14 while it is $6.52 in location b. Therefore, location b has lower rent per passerby.
