How can i solve this problem? A recent report shows that 62% of people are interested in black holes. If this number is down from the previous year by 8%, what was the percent of people who were interested last year?

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)
