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
To predict your wages if you assemble 100 phones in one day, we can use the equation y = 0.75x + 30, where x = 100.
Substituting x = 100 into the equation:
y = 0.75(100) + 30
y = 75 + 30
y = 105
Your wages for assembling 100 phones in one day would be $105.
