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 phone in one day, using the equation of the trend line y equals 0.75 x plus 30,, where x is the number of phones assembled in one day and is the total wages. Write your wages in dollars and cents.

Answer 1

Using the equation y = 0.75x + 30, where y is the total wages and x is the number of phones assembled in one day:

y = 0.75(100) + 30
y = 75 + 30
y = 105

Therefore, if you assemble 100 phones in one day, your wages would be $105.
