Question 59:
Jackie's sisters weigh 114 lb, 140 lb, 120 lb, and 129 lb. The average female in her city weighs 139.1 lb. How much does Jackie weigh if she and her sisters have an average weight of 139.1 lb? (Round the answer to the nearest tenth)

Question 60:
To get a C in history, Nandan must average 71 on four tests. Scores on the first three tests were 68, 78, and 61. What is the lowest score that Nandan can get on the last test and still receive a C? (Round the answer to a whole number)

To find Jackie's weight, first add up the weights of her sisters: 114 lb + 140 lb + 120 lb + 129 lb = 503 lb. If Jackie and her sisters together have an average weight of 139.1 lb, and there are 5 of them, their total weight should be 139.1 lb * 5 = 695.5 lb.

Therefore, Jackie's weight should be the total weight less the combined weight of her sisters, or 695.5 lb - 503 lb = 192.5 lb.

For Nandan's test score, the total points required for a C is 71 * 4 = 284. The sum of his first three tests is 68 + 78 + 61 = 207. So, the lowest score he can get on his last test to still receive a C is 284 - 207 = 77.
