the ST problem is:

A. What is the cost of the toaster to the retailer?

B What is the rate of markup on cost?

ND Problem is:

If the rate of markup on selling price of lettuce in a grocery store is 60%, what is the rate of markup on cost?

3rd problem is:

Workers World bought 250 pairs of rubber boots at $15 per pair. The manager applies a 90% rate of markup on cost when pricing footwear. What is the operating profit per pair if overhead expenses work out on average to be 20% of the selling price?
