Question

1.) Besides showing the number of pairs of shoes, harnesses, and chalk bags rented by three groups of climbers, the table shows the total cost of the rentals for each group. Which system of linear equations will help you find the cost of renting each item?
2.)What is the cost of renting each item? (Hint: Solve the system of equations you selected in the previous problem, for x, y, and z.)

Answer 1

You have to make the linear equations which are:
4Shoes + 5Harnesses +1Bags = 23
6Shoes + 6Harnesses + 0Bags = 30
3Shoes + 7Harnesses + 5Bags = 28
