A store bought 100 toys at a cost of ​$20 each. The store sold all the toys at a percent markup of 15%

. Find the total selling price.

The percent markup of 15% means that the selling price is 115% of the cost price.

So the selling price of each toy is $20 x 1.15 = $<<20*1.15=23>>23.
The total selling price is $23 x 100 = $<<23*100=2300>>2300. Answer: \boxed{2300}.
