Answer:
60-inch TV = $1,955
the remote control = $115 
the installation service = $230
Explanation:
if someone purchased the items included in the package separately, they would cost:
60-inch TV $2,040 
the remote control $120 
the installation service $240
total $2,400
we must determine the weighted average of each item:
60-inch TV ($2,040/$2,400) x 100 = 85% 
the remote control ($120/$2,400) x 100 = 5%   
the installation service ($240/$2,400) x 100 = 10%
now we multiply by the package's price:
60-inch TV 85% x $2,300 = $1,955
the remote control 5% x $2,300 = $115 
the installation service 10% x $2,300 = $230
