84. In 2010, Target had 355,000 employees. By 2015 , due to mon ,
ste closures, the number of employees was reduced to \( 347 \mathrm{~m}^{2} \). Let \( y \) be the number of Target employees in the year \( x \), whthe \( x=0 \) represents 2010. (Source: Target Corporation)
a. Write a linear equation that models the decreane in the number of Target employees, in terms of 18 year \( x \).
b. Use this equation to predict the number of Target er ployees in 2018.
