Margo paid $550.00 for dance classes. She paid a $50.00 registration fee and $25.00 for each week she was enrolled in the classe
trapecia [35]

Answer:

She enrolled in the dance classes for 20 weeks

Step-by-step explanation:

* Margo paid $550.00 for dance classes

* She paid a $50.00 registration fee

* She paid $25.00 for each week she was enrolled in the classes

* We need to find the number of weeks w she enrolled in the

  dance classes

<u><em>Lets write an equation of these information and solve it</em></u>

∵ The registration fee = $50

∵ The cost of of each week = $25

∵ The number of weeks = w

She will pay $50 plus $25 times the number of the weeks

∴ She paid in the dance classes = 50 + 25 w

∵ She paid $550 for the dance classes

∴ 50 + 25 w = 550

The equation is 50 + 25 w = 550

<u><em>Lets solve the equation</em></u>

∵ 50 + 25 w = 550

Subtract 50 from both sides

∴ 25 w = 500

Divide both sides by 25

∴ w = 20

∵ w represents the number of the weeks

∵ w = 20 weeks

<em>She enrolled in the dance classes for 20 weeks</em>

A recipe Requires 1/8 cup of oil for everyone half cup of water how much oil in cups is needed per cup of water
DaniilM [7]

Answer:

1/4 cup of oil for every 1 cup of water

Step-by-step explanation:

Lets take a look at the information given in the question

The recipe requires 1/8 cup of oil for every 1/2 cup of water.

We know that 1/2 + 1/2 is 1/1, or just 1 simplified

So if we are doubling the amount of water in the recipe, we have to do the same to the oil.

1/8 + 1/8 = 2/8, or 1/4 simplified

So the answer is 1/4 cup of oil to every 1 cup of water
