The word problem is: Nancy's quiz average is a 74. Her quiz average is 1/4 of her grade. The test average is 3/4 of the total grade. What test average does she need to get at least an 88? Would you be able to set up an equation, and explain how the answer was acheived? Thanks!!!

From what the problem says, you need to add 1/4 of the quiz average to 3/4 of the unknown to get the total test average.
I hope this helps. Thanks for asking.
