LARUISE D
A dealer purchased 30 television sets at an average price of 2,580. He purchased the same
type 15 sets more at an average price of 3540. Calculate the average price of all sets.​

Answer 1

Answer:

2900

Step-by-step explanation:

For first 30 Tv set, average price for one Tv is 2580. So Price of all those 30 Tv = 30*2580=77400

Now, for other 15 Tv, average price for one Tv is 3540. So Price of all those 15 Tv = 15*3540=53100

total number of Tv =  30+15 = 45.

Price of all 45 Tv = Price of 30 Tv + Price of all 15 Tv

                            = 130500

Average of one Tv = (total price of 45 Tv)/45

                               = 130500/45 = 2900
