Answer:
Year - (1993 - 1995)
Step-by-step explanation:
Rate of change in the number of toys sold = [tex]\frac{\text{change in number of toys sold}}{\text{Time interval}}[/tex]
In the interval (1990 - 1993),
Rate of change in number of toys sold = [tex]\frac{32000-20000}{1993-1990}[/tex]
= [tex]\frac{12000}{3}[/tex]
= 4000
In the interval (1993 - 1995),
Rate of change = [tex]\frac{42000-32000}{1995-1993}[/tex]
= [tex]\frac{10000}{2}[/tex]
= 5000
In the interval (2000 - 1995),
Rate of change = [tex]\frac{57000-42000}{2000-1995}[/tex]
= [tex]\frac{15000}{5}[/tex]
= 3000
In the interval (2006 - 2000),
Rate of change = [tex]\frac{63000-57000}{2006-2000}[/tex]
= [tex]\frac{6000}{6}[/tex]
= 1000
Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
