Question

Crystal's mud mask costs $23 for a 0.45 oz jar. She found the same mud mask online for $72. What is the size of the jar Crystal found online?

Answer 1

Because .45 divided by 23 is .0195621739
That is how much it is per dollar
That answer times 72 is 1.408695652
So the size of the jar is about 1.41 oz
