Question

Celene need to but icing to frost some cupcakes. She writes the rule 0.1c = i to model her situation. In her rule, c represents the number of cupcakes, and i represents the total amount of icing she will need in ounces . Question 3( how many ounces of icing will celene use to frost 1 cupcake?) question 4( if celene needs 15 ounces of icing, how many cupcakes is she frosting ?)

Answer 1

Question 3:
`0.1\ ounces`

Question 4:
`150\ cupcakes`

Explanation:

Given the rule:

`0.1c = i`

We know that "c" is the number of cupcakes and "i" is the total amount of icing Celebe will need in ounces.

Question 3

In order to calculate the amount of ounces of icing Celene will use to frost 1 cupcake, you need to substitute
`c=1` into
`0.1c = i` and evaluate.

Then, you get:

`0.1(1) = i\\\\i=0.1\ ounces`

Question 4.

If Celene needs 15 ounces of icing, you must subsitute
`i=15` into
`0.1c = i` and solve for "c" in order to find the number of cupcakes she is frosting.

Then:

`0.1c = 15\\\\c=(15)/(0.1)\\\\c=150`
