Xio just took a math test with 25 questions, each worth an equal
number of points.
The test is worth 100 points total. If a score of 70
points earns a grade of C, how many questions would Xio need to get
right to get a grade a of C on the test?
X = number of points per question 25 * x = 100 x = 100/25 x = 4 let y = number of questions right 70 = y*4 y= 70/4 y = 17 r 2 Must round up to fall in the grade boundary: = 18 question right
