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=0.75x+30

, where x
is the number of phones assembled in one day and y
is the total wages. Write your wages in dollars and cents.(1 point)

To calculate your total wages using the given equation \( y = 0.75x + 30 \), where \( x \) is the number of phones assembled:

Given:

  • \( x = 100 \) (the number of phones you assembled)
  • The formula for wages: \( y = 0.75(100) + 30 \)

Now, substitute \( x \) into the equation:

\[ y = 0.75 \times 100 + 30 \] \[ y = 75 + 30 \] \[ y = 105 \]

Thus, your wages for assembling 100 phones in one day would be $105.00.
