Let the first purchase be two blades and two screws, costing $2(120+9)=258$ tugriks. Since the cost of the purchase is more than 250 tugriks, Carlson can buy the third blade with a $20\%$ discount, spending $120 \cdot 0.8=96$ tugriks. Therefore, in total, Carlson will spend $258+96=354$ tugriks.

## Answer

He can.

To repair the propeller, Karlson needs to buy three blades and one screw. In the store, blades cost 120 tugriks each and screws cost 9 tugriks each. However, after a purchase of at least 250 tugriks, a $20 \%$ discount is given on all subsequent purchases. Will Karlson be able to repair the propeller if he has only 360 tugriks with him?
