Mrs. Jenkins is giving her students an Algebra test over systems of equations. She tells her students that the test has 38 questions worth 100 points. Each problem on the test is worth either 5 points or 2 points. She tells her students that she will give them extra credit on the test if they can figure out how many of each type of problem are on the test. How many of each type of problem are on the test?
take the no. of 5 point and 2 points question be x and y respectively
after this formulate the equation : frst condition is that toatl no. of questions equal to 38 that is : x+y= 38
w8 i m telling u d steps
next equation u get is : 5x+2y= 100
solve both equations to get x and y
ok..thank you so much :)
