Angel answered 8 questions correctly and 18 questions incorrectly. How many points did he have at the end of the game? Express you answer as an integer.

-10

Step-by-step explanation:

Just set up a simple equation.

-10 Points

Step-by-step explanation:

Assuming we are finding the total points, lets use X for correct answers, and Y for incorrect.

We can make an equation that will look something like this:

10x - 5y = t (total)

Now we can plug in our values and find the total!

10(8) - 5(18)

80 - 90

-10 = t

The player has a total of -10 points at the end of the game
