150 + 20x, where x is the number of cellphones sold
Answer:?
Step-by-step explanation:
Answer:
y = $100 + $25x
Step-by-step explanation:
y is the total cost
x is the number of months
The sign up fee is $100.
Each month would cost an additional $25 per month.
The total cost then would be the sign up fee plus the $25 for each month. Since we do not know the number of months, we will assign x.
So the equation would be:
y = $100 + $25x
"Classify the polynomial by the number of terms" means a term contains both the variables and its coefficient. For example a "monomial" has one term like
.
A binomial has 2 terms like 
A trinomial has 3 terms like 
And a polynomial has 4 or more terms.
So basically one can classify the type of polynomial by counting the number of terms in a given equation.
