Answer: Janice is 1 inch taller than Krysta.
Step-by-step explanation:
Let the height of Krysta denoted by h .
According to the given statements , we will write height of each person in terms of 'h'.
Kathleen is 6 inches shorter than Krysta.
i.e. Height of Kathleen = h-6
Evan is 13 inches taller than Kathleen.
i.e. Height of Evan = (h-6)+13=h-6+13=h+7
i.e. Height of Evan =h+7
David is 2 inches shorter than Evan.
i.e. Height of David = (h+7)-2 =h+7-2
Height of David =h+5
Janice is 4 inches shorter than David.
i.e. Height of Janice= (h+5)-4=h+1
i.e. height of Janice = height of Krysta+ 1 inch [∵ h= height of Krysta]
⇒ Janice is 1 inch taller than Krysta.
