Since the rate of the other store is not given, let us just get the sales price of the skirt Dima bought from the discount store.
Original price : $54
Discount rate : 30%
$54 x 30% = $16.20 value of the discount
$54 - 16.20 = $37.80 discounted price.
Since Dima's friend told her she could have had a better deal at a different store, this means that the discount rate is higher than 30%. Let us assume that the discount is 35%
$54 x 35% = $18.90 value of the discount
$54 - 18.90 = $35.10 discounted price.
Discount store: $37.80
Different store: $35.10
Different store sales price is cheaper by $2.70

Answer:
The third option is correct
Step-by-step explanation:
We can rule out the first option because systems of equations CAN have decimal answers (this certain question cannot because of the domain) Same for the second option.
The last option says that all the numbers of forks knives and spoons must be equal but the question never specified that, in fact it looks like that is impossible since the variables have different coefficients.
The only logical answer is number 3
