Answer:
Jerry's kitten is 14cm tall at the age 4 months
Explanation:
We know that Jerry's kitten measures 19cm at 6 months, if during the month 5 to 6 it grew 2 cm, we have to subtract them to know how much he measures in month 5
19cm - 2cm = 17cm
Jerry's kitten is 17cm tall at the age 5 months
We know that Jerry's kitten measures 17cm at 5 months, if during the month 4 to 5 it grew 3 cm, we have to subtract them to know how much he measures in month 4
17cm - 3cm = 14 cm
Jerry's kitten is 14cm tall at the age 4 months
