If Jillian must average at last 90 on two quiz scores before she can move on the next skill level. Jillian got a 92 on her first quiz. What scores could jillian get on her second quiz in order to move to the next skill level
To determine the scores Jillian could get on her second quiz, we need to consider that she must average at least 90 on both quizzes.
Let's denote the score Jillian can get on her second quiz as "x".
To find the range of values for "x", we can set up an equation:
(92 + x) / 2 ≥ 90
We divide by 2 on both sides because we are looking for the average score.
First, let's solve the inequality:
92 + x ≥ 180
Next, we can subtract 92 from both sides:
x ≥ 88
Therefore, Jillian must score at least 88 on her second quiz in order to move on to the next skill level.
