Beyond the Answer
To find out what Kylee needs to score on her next test to raise her average to 78, you can start by calculating the current total of her scores: 81 + 75 + 76 = 232. To have an average of 78 over four tests, the total score needs to be 78 × 4 = 312. Subtracting her current total from the target gives us 312 - 232 = 80. So, Kylee must score 80 on her next test! If you want to double-check your work or tackle similar problems in the future, remember: always set up the equation for averages clearly! It helps to break the problem down step by step and keep track of your totals. A common mistake is to overlook the number of tests involved—be sure to use the right number when calculating the target average!
