What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that the studio charges an initial studio-use fee of $200 plus an hourly fee of $100.
From the given data the equation is formed as:-
P = 200 + 100t
Here, P is the total charges and t is the time in hours and 200 is the fixed charge.
At t = 1 hour, P = 200 + 100 = $300
At t = 2 hour P = 200 + ( 20x 100 ) = $400
Hence, the expression is P = 200 + 100t.
