Common difference is -2.5
answer is an = 15.5 - 2.5n
The combined length for three shortest jumps is 43 feet. We can find out by analyzing the graph and its entities.
What are graph and entities ?
A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Entity is any data or any existing object .
From the graph:
14*1/4 feet = by 2 students
14*1/2 feet = by 3 students
14*3/4 feet = by 1 student
15 feet = by 1 student
So the three shortest jumps are 14*1/4 , 14*1/4 , 14*1/2.
Total distance = 57/4 + 57/4 + 58/4
= 43 feet.

The graph shows that the answer would be A) pi/4 units to the right.
250$÷5=50
each people 50
3 sister = 150
2 nephews = 100
spend 10$ to each sister
100$N - 30$spend =70$N
3S= (150$ + 30$ )
= 180$÷3
=60$
2N=70$÷3 =23.33$
