Answer:
Marked up $78 and the list price is $198
Explanation:
To find a mark-up, create a proportion of ratios. Since $120 is 100% of the cost then 165% will be the mark up.
![(165)/(100)=(x)/(120)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xy7ufci744pfunax31sf8y6pv8f3zt8ai7.png)
Solve by cross multiplying.
165(120) = 100x
19,800 = 100x
198 = x
This is 78 more than 120.
