Answer:
Below.
Step-by-step explanation:
Total scores = 6*90 = 540.
He had more than one 89 ( mode) and max score - min score = 18.
Let max score = x then min = x-18.
Lets say he has 3 89's then
x + x - 18 + 3*89 + y = 540 where y is another score then:
2x + 249 + y = 540
2x + y = 291
x = 98 and y = 95 will fit this so the<em> </em>6 scores could be
80, 89, 89, 89, 95, 98.
