### Instruction: Eighteen hours ago, Beth and I took 100 photographs of our project. Today, Beth and I will take 20% fewer photographs of the same project. If we were to take 300 photographs of the project, how many photographs would we take to reach the target?### Response: If you took 100 photographs of the project 18 hours ago, and the number of photographs today is 20% fewer, then there are 20/100*100 = 20 fewer photographs of the project.
Today, you'll take 100-20 = 80 photographs of the project.
The total number of photographs of the project that you'll take is 80+100 = 180
Since the target number of photographs is 300, the number of photographs that you'll take to reach the target is 300-180 = 120
The answer is 120
