Answer: He need to score 100 in next assignment to can get an A.

Step-by-step explanation:

Given: Average marks till now = 88%

Average = (sum) divided by (Number of observations)

Here, number of assignments =7

So, [tex]88=\dfrac{(sum)}{7}\Rightarrow\ sum =88\times7= 616[/tex]  (i)

After next assignment, number of assignments = 8

Required Average = 89.5

[tex]89.5=\dfrac{sum}{8}\Rightarrow\ sum = 89.5\times8= 716[/tex]   (ii)

(ii)-(i) gives 100

So, he need to score 100 in next assignment to can get an A.
