A history teacher is writing a test worth 100 points. She uses multiple choice questions worth 6 points each and true/false questions worth 2 points each. She wants the test to have three times as many multiple choice questions as true/false questions. Let m represent the number of multiple choice questions on the test, and let t represent the number of true/false questions. Which system of equations can be used to find how many of each type of question she should write?

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
