Question

A 30 Oz box of Lucky Charms cost $4.50 a 20 oz box cost $3.60 what is the unit price of each box

Answer 1

We need to find the unit price of each box.

So, a box that weighs 30 Oz costs $4.50.

lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.

Unitary method is a process to find the value of a single unit.

Now,

30 Oz costs $4.50

therefore, 1 Oz should cost:

$\frac{4.50}{30} =0.15$ dollars

So, the unit price of box 1 is $0.15.

Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.

Now,

20 Oz box costs $3.60

therefore, 1 Oz should cost:

$\frac{3.60}{20} =0.18$ dollars

So, the unit price of box 2 is $0.18.
