A one solution I hope that help
Hello from MrBillDoesMath!
Answer:
-6.9
Discussion:
1.3n - 0.03 = -9 => multiply both sides by 100
130n - 3 = -900 =>
130n = -900 +3 = -897 => add 3 to both sides
n = -897/130 =>
n = - (69 * 13)/ (10*13) =>
n = - 69/10 = - 6.9
Thank you,

<span>The possible price of the magazine can be either $ 9 , $ 6 , or $3
First we need to understand the different between a cost and a price. A cost is the amount of money needed to Produce the magazine, while a price is the amount of money that the sellers get when he hand it over to customer
since its said the cost is in multiple of $ 3 , the possible price of two magazine would be :
$ 9 + $3 = $ 12
$6 + $6 = $ 12
$3 + $ 9 = $ 12</span>
