Frank is a software salesman. let y represent his total pay (in dollars). let x represent the number of copies of history is fun he sells. suppose that x and y are related by the equation 1900 + 110 x = y.
answer the question below

note that a change can be an increase or a decrease for an increase, use a positive number. for a decrease, use a negative number.

what is the change in frank's total pay for each copy of history is fun he sells?

what is frank's total pay if he doesn't sell any copies of history is fun?

part 1:  110 dollars

part 2: 1900 dollars

Step-by-step explanation:

what is the change in Frank's total pay for each copy of history is fun he sells?

We know y = 110x + 1900

if he sells 1 copy of history is fun (x = 1), his salary is

y = 110x + 1900

y = 110(1) + 1900 = 2010

if he sells 2 copy of history is fun (x = 2), his salary is

y = 110(2) + 1900 = 2120

Hence, his change in total pay for each copy is 2120 - 2010 = 110 dollars

what is Frank's total pay if he doesn't sell any copies of history is fun?

if he doesn't sell any copy, then x = 0, we plug that in into the formula, so his pay is

y = 110x + 1900

y = 110(0) + 1900

y = 1900 dollars

Hence, total pay is 1900 dollars if he doesn't sell any copy of history is fun.
