The classes at the middle school want to raise money the six grade runs a bake sale for 5 hrs. and make 170.00 the seventh grade sets up a ducking booth and makes 112.00 the eighth grade has a car wash and makes 192.00 in 6 hrs. which class has the highest rate for raising money.?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
