Keiko is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of History is Fun she sells. Suppose that x and y are related by the equation 2200+90x=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 Keiko's total pay for each copy of History is Fun she sells?
What is Keiko's total pay if she doesn't sell any copies of History is Fun?
Can someone add the way to do it instead of just giving the answer! Teach to fish instead of giving out the fishes just like those people!
90
2200
To find the change in Keiko's total pay for each copy of History is Fun she sells, we need to calculate the coefficient of x in the given equation.
The given equation is: 2200 + 90x = y
Since y represents Keiko's total pay, the coefficient of x (90) represents the change in her pay for each copy of History is Fun she sells. Therefore, the change in Keiko's total pay for each copy of History is Fun she sells is $90.
Now, to find Keiko's total pay if she doesn't sell any copies of History is Fun, we can substitute x = 0 into the equation and solve for y.
2200 + 90(0) = y
2200 + 0 = y
y = 2200
Therefore, Keiko's total pay if she doesn't sell any copies of History is Fun is $2200.
