Answer:

15n+21

Step-by-step explanation:

The carpet costs $15 for every n square metres so we need to multiply $15 by n so

$15*n = $15n

We have to add another $21 for delivery charge so

($15n)+21 = $(15n+21)

So the final answer is $(15n+21) and it is the third option.

Currently, the number of people entering a shopping mall is 109. It is estimated that the number of people entering the shopping

Answer:

96 people.

Step-by-step explanation:

Exponential equation for a decreasing amount:

The exponential equation for a decreasing amount is given by:

$A(t) = A(0)(1-r)^t$

In which A(0) is the initial rate and r is the decay rate, as a decimal.

Currently, the number of people entering a shopping mall is 109.

This means that $A(0) = 109$

It is estimated that the number of people entering the shopping mall will decrease by 3% each hour.

This means that $r = 0.03$

$A(t) = A(0)(1-r)^t$

$A(t) = 109(1-0.03)^t$

$A(t) = 109(0.97)^t$

Find the total number of people entering the shopping mall at the end of 4 hours.

This is A(4). So

$A(4) = 109(0.97)^4 = 96.49$

Rounding to the nearest whole number, 96 people.
