Mr. lucido purchases a new video game system that is on sale for 35% off the regular retail price. if the retail price is $429, what is the final cost including a 5% sales tax? Round your answer to the nearest cent. Regular Price: $
35% Discount amount: $
sale price: $
5% tax: $
final cost: $

Regular price: $429

35% discount: 278.85

5% tax: $13.94

Final cost: 292.79

Step-by-step explanation:

regular price=$429

0.35(429)=150.15

429-150.15=278.85

35% discount amount: $278.85

278.85(0.05)=13.94

278.85+13.94=292.79

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
