How many cars drove over 35 miles per hour?

0.0075(0.75%) times 800= 6

Since .75% exceeded the speed limit or 25 by more then 10 miles, 25+10=35. so fill in .75%, then convert that to a decimal, so .0075, the multiply .0075 by 800. And easier way to do this is find what 1% of the drivers are, (8) divide that by 4 (because 75 is 3/4ths), and then multiply by 3 ( because 3 is the top number), and get 6.

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)
