Rufina [12.5K]

Answer:

<u>The equation is x = y * 4/5  and US$ 12 would equal 15 Swiss Francs</u>

Step-by-step explanation:

<u>1. Let's review all the information provided for solving this question:</u>

1 US$ equivalent to 1 1/4  Swiss Franc

2. Let's write and solve a multiplication equation to find the amount  of US$ that would equal 15 Swiss Francs

x = Amount of US$ equivalent

y = Amount of Swiss Francs

x = y /1.25

x = y / 5/4 (1.25 = 5/4)

<u>x = y * 4/5</u>

Now, let's replace with the real values:

x = 15 * 4/5

x = 60/5

<u>x = 12</u>

<u>US$ 12 would equal 15 Swiss Francs</u>
