b) 9
c) 10
d) 11

Answer 1

Stacy will need to spend 8 days on vacation to take a total of 18 pictures, as she takes 2 pictures per day in addition to the initial 2 she has already taken.

Step-by-step explanation:

Stacy has taken 2 pictures before her vacation starts, and she will take 2 pictures each day during her vacation. To calculate the number of days she needs to reach a total of 18 pictures, we can create a simple equation: Initial Pictures + (Pictures per Day × Number of Days on Vacation) = Total Pictures.

Plugging the values we know into the equation gives us 2 + (2 × Number of Days on Vacation) = 18.

To find the Number of Days on Vacation, subtract the initial pictures from the total pictures, which gives us 18 - 2 = 16. Since Stacy takes 2 pictures every day, divide the remaining pictures by the number of pictures taken per day: 16 / 2 = 8.

Therefore, Stacy needs to spend 8 days on vacation to have taken 18 pictures in total.
