karen's first five grades are: 92,88,99,97 and 89. If she has an average of 94, she'll get an A on her report card. Find Karen's average. Will Karen get an A or a B?
92 + 88 + 99 + 97 + 89 = 465
465 / 5 = 93
suppose you wanted to place 1,000,000 pennies in large coin banks.if you put 50,000 pennies in each bank,in which bank would you find the 678,230th penny
To find Karen's average, we add up her grades and divide by the number of grades she has.
94 (the desired average) is the sum of all her grades divided by 5 (the number of grades).
To find the sum of her grades, we add up 92 + 88 + 99 + 97 + 89 = 465.
Therefore, Karen's average is 465 / 5 = 93.
Since her average is 93, which is lower than 94, Karen will get a B on her report card.
