2nd answer

Answer 2

Thanks! How did you figure that out?

Answer 3

in group A:
take cost of a pair of shoes as x. Since there are 4 pairs rented, the total cost for shoes will be 4x.
Use the same method to figure out total costs for Harnesses and chalk bags.
The answers will be 5y and 1z respectively.
Then add all the total costs and equal it to the final big total cost.
4x + 5y + z = 23

Answer 4

You can follow the same method of group B and group C as well
