Answer:
For any time period less than 2 hours Ian will charge less than Grayson
....
Step-by-step explanation:
We have given that:
Grayson charges $35 per hour plus a $35 administration fee for tax preparation. Ian charges $45 per hour plus a $15 administration fee
The equation we get is:
45h + 15 ≤ 35h + 35
Combine the like terms:
45h-35h ≤ 35-15
10h ≤ 20
Divide both sides by 10
10h ≤ 20/10
h ≤ 2
At 2 hours the charge is the same for both services.
For any time period less than 2 hours Ian will charge less than Grayson
