Application: Sales and Discounts
Master Application: Sales and Discounts in Grade 10 math. ### Property Composite functions can model real-world situations involving multiple sequential steps.
Key Concepts
Property Composite functions can model real world situations involving multiple sequential steps, such as applying several discounts to a price. If a sale discount is represented by $s(p)$ and an employee discount by $d(p)$, the final price is found with the composite function $d(s(p))$, where the sale price becomes the input for the employee discount.
A store offers a 15% discount, $s(p)=0.85p$. Employees get an additional 50 dollars off, $e(p)=p 50$. The final price for an employee is $e(s(p)) = e(0.85p) = 0.85p 50$.
Imagine a double discount on a new video game! First, the store applies a sale function, say 20% off. Then, you use a coupon for another 10 dollars off the sale price. We can combine these two steps into one 'super function' by composing them, $c(s(p))$, which lets you calculate your amazing final price directly from the original price tag.
