Step 1:Let&#039;s denote the score you need to earn on the next test as x.The average score of all the tests can be calculated by adding up all the scores and dividing by the number of tests. Since there are 4 tests with scores 68, 78, 90, and 91, the average is given by:68+78+90+91+x5To achieve an average of at least 85, this expression must be greater than or equal to 85. Therefore, we can write the inequality:68+78+90+91+x5≥85Step 2:To solve this inequality, we can first multiply both sides by 5 to eliminate the fraction:68+78+90+91+x≥85×5Simplifying the right side:68+78+90+91+x≥425Combining like terms:x+327≥425Step 3:Next, we isolate the variable x by subtracting 327 from both sides of the inequality:x≥425−327x≥98Therefore, the lowest score you need to earn on the next test to achieve an average of at least 85 is 98.

Result:98Solution:Let&#039;s denote the score on the next test as x. The average of all the test scores should be at least 85, so we can write the inequality as:68+78+90+91+x5≥85To solve this inequality, we can start by simplifying the left side of the equation:327+x5≥85Next, we can multiply both sides of the inequality by 5 to eliminate the fraction:327+x≥425To isolate x, we subtract 327 from both sides of the inequality:x≥425−327Simplifying further, we have:x≥98Therefore, the lowest score you need to earn on the next test to achieve an average of at least 85 is 98.
