A student has received scores of 88, 82, and 84 on the three quizzes. If tests count twice as much as quizzes, what is the lowest score the student can get on the next test to achieve an average score of at least 70?
------------------------------
Equation:
Let "x" be the lowest score the student can get>
----
(88+82+84+x)/4 >= 70
254+x >= 4*70
x >= 280-254
x >= 26
