In Mona’s new video game she earns 30 points for each fish caught and 80 points for each octopus captured, but she loses 15 poin
ts every time she captures a crab. Which expression represents the total number of points Mona will earn if she catches x fish, y octopi, and z crabs? 95 (x + y minus z)
110 (x + y) minus 15 z
30 x + 80 y minus 15 z
30 + x + 80 + y minus 15 + z
To simplify that question, you would normally say "20 is 80 percent of what number" To find the answer you must grab the number 20 and divide it by 80% or 0.8 20 ÷ 80% = 25 20 ÷ 0.8 = 25 There are 25 questions onthe exam
