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 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

Answer 1

Answer:

30x + 80y - 15z

Step-by-step explanation:

she earns 30 points for each fish caught; if she catches x fish = 30x

80 points for each octopus captured; y octopi = 80y

but she loses 15 points every time she captures a crab; and z crabs = - 15z

The expression is given as;

30x + 80y - 15z

95 (x + y minus z) - Incorrect

10 (x + y) minus 15 z - Incorrect

30 x + 80 y minus 15 z - Correct

30 + x + 80 + y minus 15 + z - Incorrect
