You work for a manufacturing company on a production line that manufactures cell phones. You are paid $30 a day plus $0.75 for each phone that you assemble. Predict your wages if you assemble 100 phones in one day, using the equation of the trend line y= 0.75x + 30, where x is the number of phones assembled in one day and y= total wages. Write your wages in dolars and cents.
To predict your wages, you can substitute x = 100 into the equation y = 0.75x + 30:
y = 0.75(100) + 30
y = 75 + 30
y = 105
Therefore, if you assemble 100 phones in one day, your wages would be $105.
