Answer:

35

Step-by-step explanation:

Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.

Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.

  • v + 3.40c = 266.20
  • v + c = 103

Subtract these equations.

  • 2.40c = 163.20

Divide both sides by 2.40.

  • c = 68

Substitute this value for c into the second equation.

  • v + (68) = 103

Subtract 68 from both sides.

  • v = 35  

The number of vegetarian wraps sold amounted to 35 in total.

Answer :

  • The school cafeteria sold 35 vegetable wraps.

Step-by-step explanation:

  • Let the count of vegetarian wraps be x
  • Let the count of chicken wraps be y.

Then for the count we have :

→ count of vegetarian wraps + count of chicken wraps = 103

→ x + y = 103......[Equation (i)]

Then for the cost we have :

→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20

Dropping the dollar signs we get :

→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20

→ x + 3.40y = 266.20.....[Equation (ii)]

Substracting equation (i) from equation (ii) we get :

→ 0 + 2.4y = 163.2

→ 2.4y = 163.2

→ y = 163.2 ÷ 2.4

→ y = 68

Now, subsitute the value of y = 68 in equation (i) we get :

→ x + y = 103

→ x + 68 = 103

→ x = 103 - 68

→ x = 35

  • Hence, the school cafeteria sold 35 vegetable wraps.
