Answer 3

Calculation of Remaining Bushes to Plant

To calculate the number of remaining bushes to plant, we need to subtract the number of bushes already planted from the total number of bushes that need to be planted.

Given information: - Total number of acacia bushes to plant: 90 - Number of acacia bushes planted before lunch: 15 - Number of rowan bushes is 3 times the number of acacia bushes planted before lunch

Let's calculate the number of rowan bushes planted before lunch: - Number of rowan bushes = 3 * Number of acacia bushes planted before lunch - Number of rowan bushes = 3 * 15 = 45

Now, let's calculate the remaining bushes to plant after lunch: - Remaining acacia bushes = Total number of acacia bushes - Number of acacia bushes planted before lunch - Remaining acacia bushes = 90 - 15 = 75

- Remaining rowan bushes = Total number of rowan bushes - Number of rowan bushes planted before lunch - Remaining rowan bushes = (3 * Number of acacia bushes planted before lunch) - Number of rowan bushes planted before lunch - Remaining rowan bushes = (3 * 15) - 45 = 45 - 45 = 0

Therefore, after lunch, there are 75 acacia bushes and 0 rowan bushes left to plant.
