Aclimbing gym charges $10 to climb each day. a pair of climbing shoes costs $84. it costs $169 to buy 6 days of climbing, one pair of climbing shoes, and one harness. how much does a harness cost?

10 times how many days and then add 84 dollars and make it equal 169 dollars
So it would be
10d+84+h =169 then the six would go in for “d” like this
10(6)+84+h=169 because (h= harness cost) then you would multiply 10 times 6 witch is 60+84+h=169 then you would add 60+84 144+h=169 then u subtract 144 from both sides
144+h=169
-144 -144
h=25 the harness cost $25 I’ll explain more if u need just let me know

Just look outside and then you’ll see where the awnser is
