Betty started a health and fitness program. So far, she has lost a total of 12 pounds. She is losing an average of one-fourth of a pound per week. If she maintains her average weekly weight loss, what will be her total weight loss in 12 weeks? pounds

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)

Idk what the answer is bc i don't get it
