Answer:
She need to make 98 on the last assignment.
Step-by-step explanation:
Average = 92
x = mark on last assignment
(88 + 97 + 91 + 86 + x) / 5 = 92
To solve for x...multiply 5 on each side
<em>(88 + 97 + 91 + 86 + x) / 5 * 5 = 92*5</em>
<em>This would get of / 5 so you don't need to divide by 5</em>
362 + x = 460
Subtract 362 from each side
x = 98
