At the end of the day of teaching the skill of cutting and sewing to make capes, Ms. Ironperson and Mr. Thoro decided to go to the Shawarma Mediterranean Grill. Ms. Ironperson ordered 3 chicken shawarma wraps and 2 orders of spiced potatoes for a total bill of $42.95. Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91. What is the cost of a chicken shawarma wrap? What is the cost of one order of spiced potatoes?

a) Cost of a chicken shawarma wrap?

$10.99

b) Cost of one order of spiced potatoes?

$4.99

Step-by-step explanation:

Cost of a chicken sharwarma wrap = a

Cost of an order of spiced potatoes = b

Ms. Ironperson ordered 3 chicken shawarma wraps and 2 orders of spiced potatoes for a total bill of $42.95.

3a + 2b = $42.95 Equation 1

Mr. Thoro ordered 5 chicken shawarma wraps and 4 orders of spiced potatoes for a total bill of $74.91.

5a + 4b = $74.91 Equation 2

So we have:

3a + 2b = $42.95 Equation 1

5a + 4b = $74.91 Equation 2

We use Elimination method to solve for this.

Multiply Equation 1 by coefficient of b in Equation 2

Equation 2 by coefficient of b in Equation 1

3a + 2b= $42.95 Equation 1 × 4

5a + 4b = $74.91 Equation 2 × 2

12a + 8b = 171.80Equation 3

10a + 8b = 149.82Equation 4

Subtract Equation 3 from Equation 4

2a = 21.98

a = 21.98/2

a = 10.99

Therefore, a = Cost of Chicken sharwarma wrap = $10.99

Subtitute 10.99 for 9in Equation 1

3a + 2b = $42.95 Equation 1

3(10.99) + 2b = 42.95

32.97 + 2b = 42.95

2b = 42.95 - 32.97

2b = 9.98

b = 9.98/2

b = 4.99

b = Cost of an order of spiced potatoes = $4.99

Hence,

The cost of a chicken sharwarma wrap = $10.99

The cost of an order of spiced potatoes = $4.99

tube or goog would be a great resource to with that question
