5 hockey pucks and three hockey sticks cost $23 5 hockey pucks and I hockey stick cost $20. How much does 1 hockey puck cost? I know that I cost $3.50 but idk how to get that answer

Let hockey pucks be a

let honey sticks be b
1st eqn --> 5a + 3b = 23
2nd eqn --> 5a + b = 20
Eqn 1 - eqn 2 will give you
2b = 3
Hence b, which is one honey stick will cost 3/2 which is $1.50
Substituting b = 1.5 into eqn two will give u the answer the question is asking for
try it for yourself. (:
answer is $3.70 btw.

To find the cost of 1 hockey puck, let's analyze the information given.

Let's assume the cost of one hockey puck is represented by the variable "x."

From the first piece of information, we know that 5 hockey pucks and 3 hockey sticks cost $23. This can be represented as:

5x + 3c = 23, where c represents the cost of one hockey stick.

From the second piece of information, we know that 5 hockey pucks and 1 hockey stick cost $20. This can be represented as:

5x + c = 20.

We can solve these two equations to find the value of x, which represents the cost of one hockey puck.

First, we need to eliminate c. We can do this by subtracting the second equation from the first equation:

(5x + 3c) - (5x + c) = 23 - 20
5x + 3c - 5x - c = 3

Combining like terms:

2c = 3

Next, we can isolate c by dividing both sides of the equation by 2:

c = 3 / 2

c = 1.5

Now that we know the cost of one hockey stick is $1.50, we can substitute this value back into one of the original equations to solve for x. Let's use the second equation:

5x + c = 20
5x + 1.5 = 20

Subtract 1.5 from both sides:

5x = 20 - 1.5
5x = 18.5

Divide both sides by 5:

x = 18.5 / 5
x = 3.70

Therefore, the cost of one hockey puck is $3.70, not $3.50 as you initially stated.
