Answer: 280
Step-by-step explanation: In order to figure out how many points Kyle has in her science class, we need to find 80% of all the possible points which is 350 points.
To find 80% of 350, first write 80% as a decimal by moving the decimal point two places to the left to get .80.
Next, the word "of" means multiply, so we multiply .80 by 350.
(.80) (350) = 280
Therefore, Kylie has 280 points in he science class.
