Answer: as company A charges a fix amount $93 for any distance and company B charges variable amount starting from $65.there will be a certain mileage after that the amount charged by company B should be greater than company A.
let for greater than m mileage company A will
charge less than company B.
charge for company A for m mileage= $93
charge for company B for m mileage= $65 + $0.70*m
so,
93 ≤ 65+0.70*m
93-65 ≤ 65+0.70*m -65
28 ≤ 0.70*m
28*10 ≤ 7 *m
280 ≤ 7m
280/7 ≤ 7m/7
40 ≤ m
Ans: greater than 40 mileage Company A will charge less than Company B

Answer:
The greatest number of adults who could have purchased tickets is 105.
Step-by-step explanation:
<em>Let the number of amount of adult tickets sold out be x</em>
Therefore ,
the number of amount of child tickets sold out be 3 × x
Total amount earned = 7 × x + 4 × 3 × x
= 19 × x
According to the question ,
19 × x ≤ 2000
⇒ x ≤ 105
Hence,
The greatest number of adults who could have purchased tickets is 105.
Okay this one is pretty easy.
