What are the lengths of sides kn and nm of the kite?
kn =
units
nm =
units

Y+10= 2y+5
10=y+5
5=y

Plug this in
(5)+10=15 for KN

2x+6=3x-1
6=x-1
7=x

Plug this value in
2(7)+6
14+6= 20 for NM

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
