A diver begins at 140 feet below sea level. She descends at a steady rate of 7 feet per minute for 4.5 minutes. Then, she
ascends 112.2 feet. What is her current depth?
O -549.3 feet
O -59.3 feet
O 59.3 feet
549.3 feet

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)

Neither is the answer

The answer is c, because you subtract 18, and then divide by -3 and flip the sign.
