Step-by-step explanation:
__________________________________________________
The mean is calculated by: [the sum total of values];
divided by the number of values.
__________________________________________________
We want to find: "[the sum total of values]";
__________________________________________________
Given: 1) The mean is: 90.
2) The number of values is: 4.
__________________________________________________
So, [the sum total of values]; divided by 4; equals 90 ;
→ Write as: " [the sum total of values] ÷ 4 = 90 " ;
_____________________________________________
→ Multiply EACH side of this "equation" by "4" ;
to solve for the "[sum total of values]" ;
→ [the sum total of values] ÷ 4 * 4 = 90 * 4 ;
___________________________________________________
to get:
____________________________________________________
→ [the sum total of values] = 90 * 4 = 360 .

The answer is: " 360 ". The sum of the scores is: " 360 " .
