Jillian must average at least 90 on two quiz scores before she can move to 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?

1 answer

Jillian must average at least 90 on her two quiz scores, so the sum of her scores must be at least 90 x 2 = <<90*2=180>>180.
If she got a 92 on her first quiz, she would need to get a score of at least 180 - 92 = <<180-92=88>>88 on her second quiz. Answer: \boxed{88}.
