To predict your wages if you assemble 100 phones in one day using the equation of the trend line, you need to substitute x with 100 in the equation y = 0.75x + 30.
y = 0.75(100) + 30
y = 75 + 30
y = 105
Therefore, your wages for assembling 100 phones in one day would be $105.
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 is the total wages
