Practice finding the percent error.
Assignment
John spent $75 on a shopping trip for new clothes last week. He had expected to spend $100 on clothes. How
was the error in his estimate?
Error = (Approximate value) - (Exact value)
-$175
O -$25
O $25
O $175

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)

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85

How many is in each case if there is 12 in each case it would be 40
