A company has 300 items to post, they have packages and
swat32

Answer:

£162.35.

Step-by-step explanation:

Total of letters + packages = 300.

Number of packages =  300 * 16 / ( 16+59)

= 300 * 16/75

= 64

So number of letters = 300 - 64 = 236.

No. of first class letters = 236 * 1/4 = 59.

No. of 2nd class letters = 236 - 59 = 177.

Total cost

=  64*1.2 + 0.52*59 + 0.31*177

= 162.35.

  • Independent Variables determining it is primarily brand : Goodrich / Goodyear ; secondarily - price, mileage, time etc
