To this problem, we will first calculate the total weight gain in 7 months and will find the weight baby giraffe gained each month.

Part 1

For each month the baby giraffe gained 58 pounds of weight from birth till the seventh month.

Part 2

= 538 lb. - 132 lb.

= 406 lb.

weight baby giraffe gained each month

weight baby giraffe gained each month

                                $=\ \ \bold{\dfrac{Total\ weight\ gained\ in\ seven\ months}{Number\ of\ month\ in\ which\ weight\ gained}}$

                                $=\ \ \bold{\dfrac{406\ lb.}{7\ months}}$
