Last month, Margo bought a tree that grows 2.5cm each day. It was 5cm tall when she bought it and now it is 65cm tall. How many days has Margo owned the plant? ◻

Calculate Total Growth: First, we need to determine the total growth of the tree since Margo bought it. Current height of the tree: 65 cm Initial height when bought: 5 cm Total growth since purchase: Current height - Initial height Total growth = 65 cm - 5 cmFind Number of Days: Now, let's calculate the total growth. Total growth = 65 cm - 5 cm = 60 cmPerform Division: Next, we need to find out how many days it took for the tree to grow 60 cm. Growth per day: 2.5 cm Total growth: 60 cm Number of days = Total growth ÷ Growth per day Number of days = 60 cm ÷ 2.5 cm/dayLet's perform the division to find the number of days. Number of days = 60 cm ÷ 2.5 cm/day = 24 days

Calculate Total Growth: First, we need to determine the total growth of the tree since Margo bought it. $\newline$ Current height of the tree: $65\,\text{cm}$ $\newline$ Initial height when bought: $5\,\text{cm}$ $\newline$ Total growth since purchase: Current height - Initial height $\newline$ Total growth = $65\,\text{cm} - 5\,\text{cm}$
Find Number of Days: Now, let's calculate the total growth. $\newline$ Total growth = $65\,\text{cm} - 5\,\text{cm} = 60\,\text{cm}$
Perform Division: Next, we need to find out how many days it took for the tree to grow $60\,\text{cm}$ . $\newline$ Growth per day: $2.5\,\text{cm}$ $\newline$ Total growth: $60\,\text{cm}$ $\newline$ Number of days $= \frac{\text{Total growth}}{\text{Growth per day}}$ $\newline$ Number of days $= \frac{60\,\text{cm}}{2.5\,\text{cm/day}}$
Perform Division: Next, we need to find out how many days it took for the tree to grow $60\,\text{cm}$ . $\newline$ Growth per day: $2.5\,\text{cm}$ $\newline$ Total growth: $60\,\text{cm}$ $\newline$ Number of days $= \frac{\text{Total growth}}{\text{Growth per day}}$ $\newline$ Number of days $= \frac{60\,\text{cm}}{2.5\,\text{cm/day}}$ Let's perform the division to find the number of days. $\newline$ Number of days $= \frac{60\,\text{cm}}{2.5\,\text{cm/day}} = 24\,\text{days}$
