Answer:
271 prints.
Step-by-step explanation:
So to answer the question, we need to first write a formula to find the answer.
We know that the starting price per month is 6.95 dollars.
The full price is 17.79 dollars.
So we can start this off by writing:
17.79=6.95
Now, every time Jim prints, he charges 0.04 dollars. This will add to the orginal cost, which is 6.95. And remember this isnt a single payment, but a payment that varies depending on the amount of paper, p. So we can write this as:
17.79=6.95+0.04p
6.95 wont ever change, hense why it doesnt have a variable. 0.04 however, varies depending on the amount of paper, and thats why we included the variable p.
These two values combined make 17.79, hense why it is on the opposite side of the equals sign.
So, now we need to find how many papers, p, were printed.
To find this, lets just take our equation, and solve for P like an ordinary problem:
17.79=6.95+0.04p
So first off, lets subtract the 6.95 from both sides, because that iscolates the 0.04p, which contains the variable.
Now we have:
10.84=0.04p
Now, we could divide both sides by 0.04.
But remember, the whole point of doing this is to make 0.04p into 1p.
So another way of doing this is multiplying the 0.04 by 25, since 0.04*25=1.
So lets multiply both sides by 25:
10.84*25 is 271.
Since 10*25 is 250
And
.84*25 is 21.
So now we know:
271=1p
So 271 is your answer!
Hope this helps!
