The formula P=9d+320 is the cost of buying an article bought if P=#797.00
Find the number of the article
so you just need to solve
9d+320 = 797
9d = 477
d = 53
Well, let's plug in the given cost, P=#797.00, into the equation P=9d+320 and solve for d:
797 = 9d + 320
Subtracting 320 from both sides, we get:
477 = 9d
Dividing both sides by 9, we find:
d = 53
So, the number of the article is 53.

To find the number of the article, we need to use the given formula P=9d+320, where P represents the cost of buying the article and d represents the number of the article.
In this case, we are given that the cost of buying the article is P=$797.00. Let's substitute this value into the formula and solve for d:
797 = 9d + 320
To isolate the variable d, we can subtract 320 from both sides of the equation:
797 - 320 = 9d
477 = 9d
Now, we can solve for d by dividing both sides of the equation by 9:
d = 477 ÷ 9
d = 53
Therefore, the number of the article is 53.
9d+ 320=797
9d=477
D=53
