John sells hamburgers ($3) and cheeseburgers ($3.50). One afternoon he sells a total of 24 burger for $79. How many of these wer
ankoles [38]

John sold 10 hamburgers and 14 cheeseburgers.

Step-by-step explanation:

Given,

Cost of one hamburger = $3

Cost of one cheeseburger = $3.50

Total burgers sold = 24

Total revenue earned = $79

Let,

Number of hamburgers sold = x

Number of cheeseburgers sold = y

According to given statement;

x+y=24   Eqn 1

3x+3.50y=79    Eqn 2

Multiplying Eqn 1 by 3

3(x+y=24)\\3x+3y=72\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(3x+3.50y)-(3x+3y)=79-72\\3x+3.50y-3x-3y=7\\0.50y=7

Dividing both sides by 0.50

\frac{0.50y}{0.50}=\frac{7}{0.50}\\y=14

Putting y=14 in Eqn 1

x+14=24\\x=24-14\\x=10

John sold 10 hamburgers and 14 cheeseburgers.

a fundraiser raised $2400 , which was 3/5 of the goal . write an equation and solve it to find the goal
GuDViN [60]

First of all, 2400=0.6x is the equation

Now, we use cross multiplication

2400/1 = 3/5x

2400*5 = 3x

12,000 = 3x

12000/3= 4000

<u>The total fundraiser goal is $4,000.</u>

Jessica, Kareem, and Lamar served a total of 64 orders Monday at the school cafeteria. Jessica served 8 fewer orders than Lamar.
sergey [27]

Answer:

Jessica: 10 orders

Lamar: 18 orders

Kareem: 36 orders

Step-by-step explanation:

Let's first designate each person with a letter.

The number of orders served by Jessica can be designated as J

The number of orders served by Kareem can be designated as K

The number of orders served by Lamar can be designated as L

We know that they all served a total of 64 orders. This can be expressed as the sum of their orders equaling 64.

J+K+L=64

We also know that Jessica served 8 fewer orders than Lamar. This can be expressed as the number of orders served by Jessica, J, being equal to Lamar's orders L minus 8.

J = L-8

Fianlly, we know that Kareem served twice as many orders as Lamar. This can be expressed as the number of order's served by Kareem, K, being 2 times Lamar's orders L.

K = 2L

With these 2 equalities, we can substitute J and K in our original equation,

J+K+L=64

with their values expressed as a subtraction or multiplication of L.

J will be substituted with L-8, and K will be substituted with 2L.

J+K+L=64

With substitutions:

(L-8) + 2L + L = 64

We can simplify this by combining the L-terms:

L + 2L + L -8 = 64\\4L - 8 = 64

Next, we'll add 8 to both sides.

4L = 72

Divide both sides by 4:

L = 18

Thus, Lamar served 18 orders.

Using our expressions, we can find how many orders the others served.

Jessica:

J = L-8\\J = 18 -8\\J = 10

Jessica served 10 orders.

Kareem:

K = 2L\\K = 2*18\\K = 36

Kareem served 36 orders.
