To find the cost of the tennis racket, we can set up a system of equations:
Let's assume the cost of the hockey stick is x dollars.
According to the given information, the tennis racket costs $12 more than the hockey stick. So, the cost of the tennis racket can be expressed as (x + $12).
The total cost of the hockey stick and the tennis racket is $31. So we can write the equation:
x + (x + $12) = $31
Now we can solve this equation to find the value of x, which represents the cost of the hockey stick.
Combining like terms, we get:
2x + $12 = $31
Subtracting $12 from both sides:
2x = $31 - $12
2x = $19
Dividing both sides by 2:
x = $19/2
x = $9.50
So, the cost of the hockey stick is $9.50.
To find the cost of the tennis racket, we can substitute the value of x back into one of the equations:
Cost of the tennis racket = x + $12 = $9.50 + $12 = $21.50
Therefore, the cost of the tennis racket is $21.50.
thank you
let h represent the cost of the hockey stick...
The tennis racket costs the price of the hockey stick plus 12 ... so
h +12
TOGETHER so add them they are ....
(hockey stick) + (tennis racket) = $31
h + h + 12 = 31
now solve for h : )
