If you order 3 chickens wraps and order 2 orders of potatoes for a total bill of $42.95 someone else orders 5 chicken wraps and 4 orders of potatoes for a total bill of $74.91. What is the cost of a chicken wrap and what is the cost of one order of potatoes

The cost of a chicken wrap is $10.99

The cost of one order of potatoes is $4.99.

Step-by-step explanation:

Let the cost of a chicken wrap be x

Let the cost of one order of potatoes be y.

From the question,

3x + 2y = $42.95 equation i

5x + 4y = $74.91 equation ii

Multiply equation i by 5

Multiply equation ii by 3

15x + 10y = $214.75 equation iii

15x + 12y = $224.73 equation iv

Subtract equation iv from equation iii. This will be:

-2y = -$9.98

y = $9.98/2

y = $4.99

Since 3x + 2y = $42.95

3x + 2($4.99) = $42.95

3x + $9.98 = $42.95

3x = $42.95 - $9.98

3x = $32.97

x = $32.97/3

x = $10.99

The cost of a chicken wrap is $10.99

The cost of one order of potatoes is $4.99.

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
