In Summer School, students need to make grades higher than 90s to be able to bring up their failing grade from low 60s to a 70. If Kayla made a 63 as her average quarterly grades, what grade should her last quarterly grade be so she will be passing? Choose the correct solution. Responses A Kayla would need to make a 77. Multiplying 63 x 4 = 252 and 70 x 4=280, which means 28 points difference/4 is 7 plus 70 = 77. Kayla would need to make a 77. Multiplying 63 x 4 = 252 and 70 x 4=280, which means 28 points difference/4 is 7 plus 70 = 77. B Kayla needs to make a 91. Add together three quarters of grades as 63s and one as a 91, divide by 4 and Kayla will pass with a 70. Kayla needs to make a 91. Add together three quarters of grades as 63s and one as a 91, divide by 4 and Kayla will pass with a 70. C Kayla needs to make a 70. She is only 7 points away from her passing score of 70. Kayla needs to make a 70. She is only 7 points away from her passing score of 70. D Kayla needs to make 28. If she is only 28 points away from passing, then 63 x 4 = 252 and 70 x 4 = 280, subtract the 280-252 = 28 points difference.
The correct solution is A. Kayla would need to make a 77. Multiplying 63 x 4 = 252 and 70 x 4 = 280, which means there is a 28 point difference. Dividing that by 4 gives you 7, and adding that to the passing grade of 70 gives a required grade of 77.
