Kendra owns a restaurant. She charges $1.50 for 2 eggs and one piece of toast, and $0.90 for one egg and one piece of toast. How much does one egg cost? How much does one piece of toast cost?

cost of egg = $0.6

cost of one piece of toast = $0.3

Step-by-step explanation:

In order to find the cost, first form equations from the given data.

Let, e = egg and t= toast

Equation 1: for 2 eggs and one piece of toast

2e + t = 1.50

t= 1.50 - 2e > eq(1)

Equation 2:  for one egg and one piece of toast

e + t = 0.90

t = 0.90 -e >eq(2)

putting above value in eq (1)

(1)=> 2e + 0.90 -e = 1.50

e = 1.50 - 0.90

e= 0.6 put the value in eq (2)

(2)=> t= 0.90 - 0.6

t= 0.3

Therefore, one egg cost $0.6 and one piece of toast cost $0.3

A single egg costs $0.60 AND

One piece of toast costs $0.30

Step-by-step explanation:

Let's assume that the cost of a single egg is X

And the cost of a toast as Y

Kendra charges $1.50 for one toast and 2 eggs

The equation above will be

2X + Y = 1.50 equation 1

And she also charges $0.90 for one egg and one piece of toast

The equation for the above statement will be

X + Y = 0.90equation 2

For equation 1, we make X the subject of the formula

X = 0.90 - Y

Now substitute for this in equation 1.

Remember that equation 1 is

2X + Y = 1.50

It will now be 2(0.90 - Y) + Y = 1.50

= 1.80 - 2Y + Y = 1.50

Y= 0.30

Therefore,the price of one toast is $0.30

And now for the price of an egg,we substitute Y = 0.30 in equation 2

X + Y = 0.90

X + 0.30 = 0.90

X = 0.60

Here the price of am egg is $0.60
