Question

Can you please help me with this question I would really appreciate it ​

Answer 1

15n+21

We dont know how much square peter buys and per square cost 15$. So thats mean peter buys 15n$

And the total delivery charge 21$

Its cost 15n+21

Answer 2

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.
