ManhattanGMAT instructors: thanks for taking the time to answer our questions!!!
I really appreciate the insight!!
Here's my question:
A retailer sold an appliance for 30% above cost, which represented a gross profit of $21. For what price did the retailer sell the appliance?
a) $27.30
b) $51.00
c) $63.00
d) $70.00
e) $91.00
This is what i'm thinking-
130%(x)=$21
but i'm missing the next step(s).....
