I assume you mean she must average 90 or more
90 = (92+x)/2
180 = 92 + x
x = 88 or more
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?
Please help me and show your work thanks
