Predict your wages if you assemble 100 phone in one day, using the equation of the trend line y=0.75+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 answer

To predict the total wages using the equation of the trend line \( y = 0.75x + 30 \), we need to substitute \( x \) with the number of phones assembled, which is 100.

Plugging the values into the equation:

\[ y = 0.75(100) + 30 \]

Calculating this step-by-step:

  1. Calculate \( 0.75 \times 100 = 75 \)
  2. Add 30 to the result: \( 75 + 30 = 105 \)

Therefore, the total wages for assembling 100 phones in one day would be:

\[ y = 105 \]

Thus, the wages would be $105.00.
