Question

11/20
the deli in the grocery store gives each customer a free cup of coffee worth $1.50.
write a function to represent the situation.
$y = 1.5x$
$y = 15x$
$x = 1.5y$
$x = 15y$

Explanation:

Step1: Define variables

Let $x$ = number of customers, $y$ = total cost of free coffee

Step2: Set up cost function

Each coffee costs $\$1.50$, so total cost is $1.50$ times number of customers.
$y = 1.5x$

Answer:

y = 1.5x
