Question

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 points every time she captures a crab. Which expression represents the total number of points Mona will earn if she catches xfish, y octopi, and z crabs?


95(x+y-z)

110(x+y)-15z

30x+80y-15z

30+x+80+y-15+z

Answer 1

Third one

Explanation:

30x would be 30 times the amount of fish (x)

+ 80y would be 80 times the amount of octopus captured (y)

- 15z would be subtracting 15 times the amount of crabs she captures
