Answer:
The simplified expression to represent the scenario is Y = 4·X - 0.48·X
Step-by-step explanation:
The given parameters are;
The number of tickets required = 4
The amount of discount offered = 12%
Let the selling price = X
Therefore the amount paid for each ticket = X - X×12 %
Which gives;
The amount paid for each ticket = X - X×0.12
The amount paid for the four tickets = 4 × (X - X×0.12) = 4·X - 4×0.12·X = 4·X - 0.48·X
Whereby the amount paid for the four tickets = Y, we have;
Y = 4·X - 0.48·X
Which gives, the simplified expression to represent the scenario as Y = 4·X - 0.48·X.
