Mr. Martin is giving a math test next period. The test, which is worth 100 points, has 29 problems. Each problem is worth either
Murrr4er [49]

Answer:

A is correct.

Step-by-step explanation:

From the second sentence , we can deduce that the total number of problems is 29.

Now, x represents the number of problems that award 5 marks, while y represents the number of problems that award 2 marks.

Hence x + y = 29.

There are a total of 100 marks. This mean each x has a mark of 5, so total x marks equal 5x. Also, each y has a mark of 2. total y marks equal 2y. Since total marks equal 100. This mean 5x + 2y = 100 which gives our second equation.

This shows A is correct.
