Answer:
what exactly did u want me to work out?
Answer:
option c
Step-by-step explanation:
a guitar 15% off means that the cost is now 85%

now the 8% of 170 is


so the total cost is
170+13.6
183.6
You can start by turning it into a mixed number:
2 4/12
then you can simplify the 4/12 part by dividing by 2/2 and getting 2/6
then you can divide 2/6 by 2/2 and get ⅓
so 28/12 simplified is 2 1/3
Hope this helped!! :D
