Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.

Step-by-step explanation:

You do not know how much a 20% discount is unless you know the price of the shirt. This can be more or less than $20, so you don’t know.

Hope this helps!

Answer:

D.

Step-by-step explanation:

For example if a shirt was $100 dollars, 100-20 = 80 and 100 x .8 = 80

But if the shirt cost $35, 35-20 = 15 while 35 times .8 = 28

This shows that the cost of the shirt is important in discovering which coupon is better.

What is the value of n
klasskru [66]

Answer:

9 + 18 = 27

27 + n + 1

= n = 27 - 1 = 26.

n = 26

9 + 18 + 26 + n + 7 =

53 + n + 7

53 + 7 + n

60 + n = 360

n = 360 - 60 = 300

so, n 300

so = 9, 18, 300, 26
