Aclimbing gym charges $10 to climb each day. a pair. of climbing charges shoes cost $84.it costs $169 to buy 6 days of climbing, one pair of climbing shoes, and one harness. how much does a harness cost? write an equation for each problem. use a variable for the unknown number. solve.

The correct answer is:

The harness is $25.

Explanation:

Let x represent the cost of the harness.

Each day of climbing is $10. This means 6 days of climbing is represented with 10(6). The shoes are $84. This makes our expression 10(6)+84. Adding the harness, x, to that, our total comes to $169. This gives us the equation

10(6)+84+x = 169

Simplifying the left hand side, we have

60+84+x = 169

Combining like terms, we have

144+x = 169

Subtract 144 from each side:

144+x-144 = 169-144

x = 25

The harness is $25.
