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>
