Answer 1

For 2.5 hours of service, the costs charged by the two companies will be same.

Step-by-step explanation:

Given equation is;

75+50x=25+70x

Arranging alike terms together;

$75+50x=25+70x\\75-25=70x-50x\\50=20x\\20x=50$

Dividing both sides by 20

$\frac{20x}{20}=\frac{50}{20}\\x=2.5$

For 2.5 hours of service, the costs charged by the two companies will be same.
