Which of the following best represents the average rate at which infants gain weight for the first six months after birth?
a. ) 1.5 pounds per day

b. ) 1.5 pounds per month

c. ) 1.5 kilograms per day

d. ) 1.5 kilograms per hour

The answer to this question is B. 1.5 pounds per month.

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)
