Step-by-step explanation:

For store A the final price for 12 packs of paper is:

= 12 packs × $3/pack = $36

For store B:

In order to get 12 packs from the special you must by 4 specials because you buy two and get one free which means you get 3 packs with each special. Therefore:

Therefore option b from store B is the best price because it is $2.4 cheaper than option a from store A

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
