The price in store A is:


(132.89\cdot(1-0.2))\cdot(1-0.2)=(132.89\cdot0.8)\cdot0.8=106.344\cdot0.8=85.0752.

The price in store B is:


132.89\cdot(1-0.4)=132.89\cdot0.6=79.734.

Finally, the price in store C is:


(132.89\cdot(1-0.3))\cdot(1-0.15)=(132.89\cdot0.7)\cdot0.85=93.023\cdot0.85=79.06955.

Answer: At store C you can get the skateboard for the lowest price.
