Answer:
a) 191.3 students
b) 433.8 students
Explanation:
a) Since x represents years since 1998, on the graph, the number of student in 2005 is represented at x = 7.
So, to solve for the number of students studying abroad in 2005, find the approximate y-coordinate of the point on the graph at x = 2005 - 1998 = 7:
(7, 191.296)
↓
191.296
Finally, round this to the nearest tenth.
192.296 ≈ 191.3 students
See the attached images for a graph and an algebraic solution for the coordinate.
b) Since x represents years since 1998, on the graph, the number of student in 2018 is represented at x = 2018 - 1998 = 20.
So, to solve for the number of students studying abroad in 2018, find the approximate y-coordinate of the point on the graph at x = 20:
(20, 433.761)
↓
433.761
Finally, round this to the nearest tenth.
433.761 ≈ 433.8 students
