Question

7. Matthew has an average of 86 in four Math tests. His next exam is on Friday.
What is the highest possible average he can have after Friday?​

Answer 1

Answer:

Highest possible average he can have is 5 Tests $= 92.8$

Step-by-step explanation:

Matthew has an average of 86 in four Maths tests.

His Sum of four tests = Average x Number of Tests = 86 x 4 = 364

Now highest possible marks Matthew can get on Friday's exam is 100.

∴ highest possible average he can have is 5 Tests $\frac{364 + 100}{5} = \frac{464}{5} = 92.8$
