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.
