Question

Joe scored 10 more than half his normal average at the basketball game tonight. If he scored 24 times, what is his usual average?

Answer 1

Answer: His usual average = 28.

Step-by-step explanation:

Let x = usual average at the basketball game tonight.

As per given,

$\dfrac{x}{2}+10=24$

Subtract 10 from both sides , we get

$\dfrac{x}{2}+10-10=24-10\\\\\Rightarrow\ \dfrac{x}{2}=14\\\\\Rightarrow\ x=14\times2=28$

Hence, his usual average = 28.
