A test is worth 20 points. Samantha scored 12 points. What is her grade as a percentage? Charlie scored 15
points. What is his grade as a percentage?

Samantha = 60%

Charlie = 75%

Step-by-step explanation:

Since the test is 20 points total you can multiply it by 5 to make any points out of the 20 become a percentage so say Samantha has a 12/20 if you multiply both by 5 you get 60/100 and say Charlie has a 15/20 you can multiply both by 5 and get 75/100

is should be y = 5x
