ANSWER:

Let the no is cans be x.

On using inverse proportionality,

480/4 = 840/x
120 = 840/x
x = 840/120
x = 7.

Hence, 7 cans cover 840sq ft.

Answer:

4 lbs left after 5 days

Step-by-step explanation:

First, you need to step up an equation!

You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.

She uses 3 1/5 pounds per day so you write:

20 - 3 1/5x

and you know that she wants to know how much she has left after 5 days so you replace the x with 5:

20 - (3 1/5) * 5

Multiply first:

20 - 16

After Subtracting you get the answer:

4 lbs left
