The formula P=9d + 320 is the cost of buying an article "p" while "d" is the number of articles bought.

if P=N797.00 find the number of articles.

then 9d + 320 = N797.00 , I assume N is some unit of money

d = N(797.00 - 320)/9 = ....

The answer

Alright, let's solve this equation and find the number of articles to make it more fun than buying them!

So, we have the equation P = 9d + 320, and we're given that P = N797.00.

Let's substitute N797.00 for P in the equation:

N797.00 = 9d + 320.

To find the value of d, we need to isolate it on one side. So, let's do some math magic:

Subtract 320 from both sides of the equation:

N797.00 - 320 = 9d.

Now, let's do some more math magic:

N477.00 = 9d.

To find the value of d, we need to divide both sides of the equation by 9:

N477.00 ÷ 9 = d.

Now, let me do some quick calculations:

d ≈ N53.00.

Therefore, the approximate number of articles you bought is 53! It seems like you've done quite a shopping spree. Enjoy your purchase and remember to always buy in moderation!

To find the number of articles, we need to rearrange the equation P = 9d + 320 and substitute the given value P = N797.00.

Let's substitute P = N797.00 into the equation:

N797.00 = 9d + 320

Now, let's isolate the variable "d" by subtracting 320 from both sides of the equation:

N797.00 - 320 = 9d

Simplifying the equation:

N477.00 = 9d

To solve for "d," we can divide both sides of the equation by 9:

d = N477.00 / 9

Calculating the value:

d = N53.00

Therefore, the number of articles bought is 53.

To find the number of articles (d) when the cost (P) is given, we can rearrange the formula P=9d + 320 and solve for d.

Given that P=N797.00, we can substitute this value into the formula:

N797.00 = 9d + 320

Now, we can isolate the variable d by subtracting 320 from both sides:

N797.00 - 320 = 9d

Rearranging further, we have:

477 = 9d

To solve for d, divide both sides by 9:

d = 477 ÷ 9

Calculating this:

d = 53

Therefore, the number of articles bought (d) is 53.
