Answer 1

Take (122-6)÷4=29 days
Answer is (c)

Answer 2

Plant will take 29 days to reach 122 cm in height .

Option (c) is correct .

Explanation:

Let us assume that x be the number of days plant will take to reach 122 cm in height .

As given

A vine 6 cm tall is planted in a garden. it grows 4 centimeters a day.

Equation becomes

Total height = Height of the plant + Height grow everyday × Number of days .

122 = 6 + 4 × x

122 = 6 + 4x

122 - 6 = 4x

116 = 4x

`x = (116)/(4)`

x = 29 days

Therefore plant will take 29 days to reach 122 cm in height .

Option (c) is correct .
