We have this:
A bracelet was marked up $175 from cost, which amounts to a 50% increase. Find the original cost of the bracelet.
A) $365 B) $360 C) $360 D) $350
Why not set up a proportion?
new price/origin price = percent/100
Let x (or any letter of choice) = the orginal price. Also, change 50% to a decimal which is .50.
We now have this proportion:
175.0/x = .50/100
Cross-multiply and then divide to find x.
Answer is D or $350.
