Karate racks = 2000
Explanation of Solution
Given information:
Selling of baseball racks are 6 times of karate belt racks.
Profit of each baseball and karate belt is $3 and $5 respectively.
The total net profit is $46000.
Calculation:
Let number of baseball racks be x, and number of karate racks be y.
The equations will be as follows:
Multiply equation (1) by 30, and rewrite the equation as follows:
Substitute the value of x in equation (2) and solve to get y.
Put value of y in equation (1) as follows:
Thus, the value of x and y are 12000 and 2000 respectively.
