Question 7

Hitman42 [59]

Answer:

$f(d) = 15 + 3d$

Step-by-step explanation:

Given

$a = 15$ --- day 1

$Rate = 3$ -- i.e. triples daily

Required

Determine the function f(d)

The number of customers on a particular day is:

Customers = Day 1 + Rate * Number of days

Represent as a function:

$f(d) = a + Rate* d$

Where d is the number of days.

So, we have:

$f(d) = 15 + 3* d$

$f(d) = 15 + 3d$
