Sam 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 110x+2200=y Answer the questions 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 Sam's total pay for each copy of History is Fun he sells? What is Sam's total pay if he doesn't sell any copies of History is fun?

To find the change in Sam's total pay for each copy of "History is Fun" he sells, we need to look at the coefficient of the variable x in the equation $110x + 2200 = y$. This coefficient represents the change in y (Sam's total pay) for each unit increase in x (the number of copies sold).<br /><br />Step 1: Identify the coefficient of x in the equation.<br />The coefficient of x is 110.<br /><br />Answer: The change in Sam's total pay for each copy of "History is Fun" he sells is $110.<br /><br />To find Sam's total pay if he doesn't sell any copies of "History is Fun," we need to substitute x = 0 into the equation and solve for y.<br /><br />Step 2: Substitute x = 0 into the equation $110x + 2200 = y$.<br />$110(0) + 2200 = y$<br />$0 + 2200 = y$<br />$2200 = y$<br /><br />Answer: Sam's total pay if he doesn't sell any copies of "History is Fun" is $2200.
