To find , we find the output when 3 is the input. By this, I mean we try to find the y when x is 3. We see that on the graph, when x is 3, y is 8. Be mindful of the scale on the y-axis, where every unit is 2, not 1.
The students have already raised $189.32 so 491.60-189.32= 302.28 is the remainder the 22 students must raise in order to final an equal amount each individual student must make divide your remainder (302.28) by the number of students (22)
