Question

I need smart one here :3

Use the five-step plan to solve the following problem. The number of international unit (IU) of vitamin A in a cup of skim milk is one ninth the number in a stalk of cooked broccoli. A person who has both the skim milk and the brocolli has recieved the recommended daily allowance of 5000 IU of vitamin A . How many IU's of vitamin A are contained in a cup of skim milk? Choices for broccoli : 500, 4500, 450

Answer 1

Dunno exactly what the five-step plan is, but i would solve it like this:

x+1/9x=5000
x=4500
so broccoli is 4500 IU and then the cup of skim milk has 500 IU
