2. Puppy B weighs 8 pounds, which is about 75% of its adult weight. What will be the adult weight of Puppy B?


3. If you haven’t already, write an equation for each situation. Then, show how you could find the adult weight of each puppy by solving the equation.
Let x
be the weight of Puppy A.

Answer 1

below

Explanation:

1) 8 = 25 percent

100 percent = 8 x 4

100 percent = 32

2) 8 = 75 percent

5 percent = 8 / 15

100 percent = 8 / 15 x 20

100 percent = 10.67

3) x = weight of puppy A

y = percentage

z = adult weight

z = x(100 / y)
