Keisha is a software saleswoman. Let y represent her total pay (in dollars). Let x represent the number of copies of Math is Fun she sells. Suppose that x and y are related by the equation 120x+ 1500 = 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.

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
