Hey there! I'm happy to help!

We have 5 test scores that give us an average of at least 75.

76, 85, 92, 63, x

We add these all up and divide by 5 to get 75.

Let's go backwards to find x.

We multiply by 5.

75(5)=375

We subtract all of the numbers except for x.

375-76-85-92-63=59

So, you need to earn at least 59 on the next test to achieve an average of at least 75.

Have a wonderful day! :D
