Isabella is making waffles. It takes of a pound of flour to make 2 waffles. She uses pounds of flour for every 8 eggs used.If Isabella uses a total of 12 eggs, then how many waffles does she make?

Respuesta :

She makes total 3 waffles.

Explanation

Suppose, the number of waffles she makes is [tex]x[/tex]

It takes 1 pound of flour to make 2 waffles. That means, for making 1 waffles she needs [tex]\frac{1}{2}[/tex] pound of flour.

So, the amount of flour needed to make [tex]x[/tex] waffles [tex]= \frac{1}{2}x[/tex] pound.

Now, 1 pound of flour is used for every 8 eggs. So, [tex]\frac{1}{2}x[/tex] pound of flour is used for [tex](8*\frac{1}{2}x)=4x[/tex] eggs.

Given that, she uses a total of 12 eggs. So, the equation will be.....

[tex]4x=12\\ \\ x= \frac{12}{4}= 3[/tex]

So, she makes total 3 waffles.
