The two designers will charge same amount for 8 hours.
Step-by-step explanation:
Designer A charges;
Initial fee = $480
Charges per hour = $105
Let,
x be the number of hours, therefore, total cost for x hours will be;
A(x) = 480+105x Eqn 1
Designer B charges;
Initial fee = $840
Charges per hour = $60
B(x)=840+60x Eqn 2
When the amount will be same, both functions will be equal, therefore
A(x)=B(x)

Dividing both sides by 45

The two designers will charge same amount for 8 hours.

Every fraction is a short way to write a division problem.
A fraction means
(the top number) divided by (the bottom number).
When you go ahead and actually do the division, the quotient you get
is the decimal form of the fraction.
Example:
Let's say you have the fraction 792 / 3168 .
Just pull out your pencil or your calculator, and divide 792 by 3168.
You'll get 0.25 . That's the decimal form of that whole ugly fraction !
