1.
A restaurant served 12,000 people in 2010. In 2012, the restaurant served 14,000 people. Write a linear model that represents the number y of people that the restaurant serves x years after 2012. Use the model to predict the number of people the restaurant will serve in 2018.
a)
y = 2000x +12000, In 2018 the restaurant will serve approximately 31,200 people
b)
y = 1500x +12000, In 2012 the restaurant will serve approximately 18000 people
c)
y = 1000x +12000, In 2018 the restaurant will serve approximately 20,000 people
d)
y = 1000x +14000, In 2018 the restaurant will serve approximately 22,000 people
