88e interprets the total cost for all the economy class seats, as all seats are sold, where 88 is the number of economy class seats and e dollars is the cost of each economy class seat.
In the question, we are given an equation, C = 24f + 88e, and are informed that the cost, C, in dollars from an airplane flight given that the average cost of a first class seat is f dollars and the average cost of an economy seat is e dollars is given by the equation above if all seats are sold.
We are asked for the interpretation about the 88e as shown in the equation.
The equation given to us is a cost equation.
A cost equation comprises of two parts:
- Per unit price
- Number of units.
In the given equation, we have two types of quantities:
- First class seats
- Economy seats
Thus, both these quantities must be having a per unit price, multiplied by the number of units sold.
Now, we are informed that e dollars is the per unit price for an economy class seat.
Thus, 88e interprets the total cost for all the economy class seats, as all seats are sold, where 88 is the number of economy class seats and e dollars is the cost of each economy class seat.
