Answer 2

Answer:

Average cost of oranges = $15.6 per dozen

Explanation:

Recall the formula,

Average =  $\frac{sum \ of \ observations }{Total \ no \ of \ observations}$

Here total no. of oranges bought =  5 dozen

The total cost of 5 dozen oranges =  Cost of 2 dozen oranges bought for 12/dozen + Cost of 3 dozen oranges bought for 18/dozen

= 12 × 2 + 18 × 3

= 24 + 54

=  78

Average cost of oranges = $\frac{Total \ cost \ of \ 5 \ dozen \ oranges}{5}$

= $\frac{78}{5}$ = 15.6

∴ Average cost of oranges = $15.6 per dozen
