Mathematics
Knowledge Bowl is a trivia competition. Each math question is worth 15 points, each science question is worth 10 points, and a team loses 5 points for answering any
question incorrectly.
On the day of the Bowl, a team attempted to answer a total of 14 questions, earning 125 points. If the team doubled the number of science questions answered correctly and
swapped the number of questions it answered incorrectly with the number of math questions it got correct, its score would have been 10 points lower. Given that m, s, and i
represent the number of each type of question answered, find a system of equations that could model this situation. Select all the equations in the system.
•5m +20s + 151 = 115
•15m + 10s - 51 - 125
•15m + 10s +51 = 125
•m+s + i = 14
•-5m +20s +151 - 115
