Answer:

A) The cost is the same at 5 months.

Step-by-step explanation:

Lets use m to represent the number of months it will take for the cost to be the same. If we set up an equation, we can write:

75 + 10m = 50 + 15m

-50 on both sides

25 + 10m = 15m

-10m on both sides

25 = 5m

Divide by 5 on both sides.

5 = m

That means it will take 5 months for the costs to be the same.

Adult weighs 12,500 pounds
it is 5 times heavier
baby = x

adult = 5x ( 5 times the weight of the baby)

divide both sides by 5

x = 12500 / 5
x = 2500
