> How tall was the tree when Vlad moved into the house?
We know that the tree grew by 26 cm per year, the current
height is 292 cm and 4.5 years have already passed, therefore the original
height was:
original height = 292 cm – (26 cm / year * 4.5 years)
original height = 175 cm
> How many years passed from the time Vlad moved in
until the tree was 357 centimeters tall?
Calculate for time using the formula:
time = (current height – original height) / 26
time = (357 cm – 175 cm) / (26 cm/ year)
time = 7 years
