Revenue = cost * number of units sold.
We need to find the percentage increase from last year to this year.
Statement 1:
Jacy sold 20% more television units this year than the same last year.
Last year = 5x
With an increase of 20%, This year = 6x
since, we don’t know the quantity sold. We cannot find the revenue.
Hence,
Insufficient.
Statement 2:
For Jacy, the average selling price per television unit this year was 10% less than the same last year.
Average selling price ( This year ) is 10% less than the average selling price (Last Year).
S.P (This year ) = 9y
S.P ( Last year) = 10y
Without knowing the quantity sold, We cannot find the revenue.
Hence,
Insufficient. Combining both statements, Revenue ( Last year) = 5x * 10y = 50xy
Revenue ( This year) = 6x * 9y = 54xy
percentage increase = (54xy - 50xy) / (50xy) *100
= (4/50)*100
=
8%
