Answer:
3000 books
Step-by-step explanation:
We know the author receives a one time fee of $2500. On top of that, the author will receive $1.50 per book sold. This is a constant rate and is linear because of this. We can use y=mx+b. M is the slope or rate of change. M here is $1.50. B is the starting value which is $2500 here.
We write y=1.5x+2500.
This equation will give the amount of money the author earns for x number of books sold. If y=7000 for the author earning 7000. We will use inverse operations to isolate and find x.
7000=1.5x+2500
7000-2500=1.5x+2500-2500
4500=1.5x
4500/1.5=x
3000=x
The answer for this is aaaaaaaaa
This is a system of equations problem that can be solved using one of three methods: <span>graphing, substitution, or <span>elimination. I'll be using substitution.
In substitution:
1) S</span></span><span>olve one equation for either variable. I'll use the first equation because its easier to solve for one of the variables. I'll be solving for y because that will allow us to solve for the value of x faster.

2) Substitute what you get into the other equation:


3) Solve your new equation in step 2 for the variable, x.

6np would be my answer i hope this helps!
250/5/8 = 250 × (8/5)
= 400
So, a sloth may move 400 units per hour.
In other words, a sloth may move in 400 units per 60 minutes.
So, it will move
= 200 units per 30 minutes.
Therefore, it will move (400 + 200) units per (60 + 30) minutes.
Hence, in 90 minutes, the sloth may move 600 units.
