Question

Maggie sold 30 boxes of cookies in 6 days. How many days will it take her to sell 100 boxes of cookies?

Answer 1

If maggie sold 30 boxes of cookies in 6days, how long will it take her to collect 100 boxes

10

Explanation:

By Comparison:

100 ÷ 30 = 3.3333333333333

Then we must have:

x ÷ 6 = 3.3333333333333

Solving for x,

x = 6 × 3.3333333333333

x = 20

By Cross Product:

(30/6) = (100/x)

The Cross Product:

(30 * x) = (100 * 6)

Solving for x:

x = (100 * 6) / 30

Answer 2

It will take her 20 days to sell 100 boxes of cookies.

Explanation:

30 boxes = 6 days

100 boxes =
`(100)/(30)` × 6

= 20 days
