Answer:
1/6 hours
Step-by-step explanation:
Given data
Company A charges
$25 per hour and a $300 equipment fee
let the number of hours be t
and the total charges be A
A=25+300t----------------1
Company B charges $50 per hour and a $150 equipment fee.
let the number of hours be t
and the total charges be B
y=50+150t----------------2
Equate 1 and 2 we have
25+300t= 50+150t
300t-150t= 50-25
150t= 25
divide both sides by 150
t= 25/150
t=1/6 hours
