Respuesta :
what you buy in total is
6 days
1 pair of shoes
1 harness
they all add up to 169
the costs area
1 day=10 (therefor 6 days=6 times 10=60)
1 pair of shoes=84
1 harness=x unknown
6days+1pairofshoes+1harness=169
so subsitute
60+84+x=169
add like terms
144+x=169
subtract 144 from both sides
x=25
harness cost $25
