C. 44
D. 25
Let X is the random number Erik thinks of, and Y is the random number Nita thinks of.
Both X and Y are in the range from 0 to 20.
<span>X<=20
Y<=20
If the difference between their two numbers is less than 10, then Erik wins.
The difference between the two numbers can be written X-Y, or Y-X depending on which number (X or Y) is greater. But we do not know that. In order not to get negative value, we calculate absolute value of X-Y, written |X-Y| which will give positive value whether X is greater than Y or not.
If |X-Y|<10 Erik wins.

Do you have a picture for this problem? There are multiple different ways to solve this problem but I'll need a picture to help you.
Considering the given linear function, we have that:
- The change for each copy that he sells is of $120.
- If he sells no copies, he makes $2400.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
His payment for x copies bought is:
y = 120x + 2400.
Hence:
- The change for each copy that he sells is of $120, as the slope is of $120.
- If he sells no copies, he makes $2400, which is the y-intercept.

Answer:3 minute
Step-by-step explanation:
Sakura speaks hungarian =150 words per minute
Sakura speaks polish =190 words per minute
and it is given she speaks 270 more words in polish than in hungarian
She speaks for a total of 5 minutes
let she speaks hungarian for t mins
therefore 
t=2 mins
therefore sakura speaks hungarian for 2 mins and polish for 3 mins
