Explanation:

Answer 2

Below.

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 6 scores could be

80, 89, 89, 89, 95, 98.
