To solve for the number of articles, we need to rearrange the formula to isolate 'd':
P = 9d + 360 (subtract 360 from both sides)
P - 360 = 9d (divide both sides by 9)
(d = (P - 360)/9)
Now we can substitute the given value of P, which is #797.00:
d = (797 - 360)/9 = 43
Therefore, the number of articles bought is 43.
The formula P=9d +360 is the cost of buying an article 'p' while 'd' is the number of article bought. if p #797.00, find the number of articles.
