What is the cost of a chicken shawarma wrap?

$10.99

What is the cost of one order of spiced potatoes?

$4.99

If x denotes the cost of a chicken shawarma wrap and y denotes the cost of an order of spiced potatoes, what are the equations needed to solve this problem?

3x + 2y = $42.95Eq 1

5x + 4y = $74.91Eq 2

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.

3x + 2y = $42.95 Equation 1

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

5x + 4y = $74.91 Equation 2

So we have:

3x + 2y = $42.95Eq 1

5x + 4y = $74.91Eq 2

We use Elimination method

Multiply Equation 1 by coefficient of y in Equation 2

Equation 2 by coefficient of y in Equation 1

3x + 2t= $42.95 Equation 1 × 4

5x + 4y = $74.91 Equation 2 × 2

12x + 8y = 171.80Equation 3

10x + 8y = 149.82Equation 4

Subtract Equation 3 from Equation 4

2x = 21.98

x = 21.98/2

x = 10.99

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

Subtitute 10.99 for 9in Equation 1

3x + 2y = $42.95 Equation 1

3(10.99) + 2y = 42.95

32.97 + 2y = 42.95

2y = 42.95 - 32.97

2y = 9.98

y = 9.98/2

y = 4.99

y = 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

I’m having a hard time understanding your question

Answer from: Quest

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
