At a cafeteria, Mary orders two pieces of toast and a bagel, which comes out to \$3.15. Gary orders a bagel and a muffin, which comes out to \$3.50. Larry orders a piece of toast, two bagels, and three muffins, which comes out to \$8.15. How many cents does one bagel cost?

Or, you can see this(This is a copy paste of what was on Brainly):

One bagel costs 155 cents.

---------------------------------

This question is solved using a system of equations.

I am going to say that:

x is the cost of a toast.

y is the cost of a bagel.

z is the cost of a muffin.

---------------------------------

Two pieces of toast and a bagel costs \$3.15.

This means that

Since we want to find the cost of a bagel, we write x as a function of y, so:

---------------------------------

A bagel and a muffin costs \$3.30.

This means that:

Since we want y:

---------------------------------

Piece of toast, two bagels and three muffins cost \$9.15.

This means that:

We have x and z as functions of y, so:

---------------------------------

In cents, one bagel costs 100*1.55 = 155.
