2 of them are priced at $10.45 each, 2 at $12.05 each, 1 at $17.50
TOTAL cost when purchased individually = (2 x $10.45) + (2 x $12.05) + (1 x $17.50)
= $20.90 + $24.10 + $17.50
= $62.50

The amount saved by purchasing the kit is what percent of the total price of the 5 filters purchased individually?
Amount saved = $6250 - $57.50 = $5.00

Percent = (100)($5.00)/$62.50
= 500/62.50
= 5000/625
= 1000/125
= 200/25
= 8%

Answer: B

The total cost of the 5 filters when purchased individually is:

2 x 10.45 + 2 x 12.05 + 17.50

20.90 + 24.10 + 17.50

$62.50

Therefore, the amount saved when purchasing them together in a kit is 62.50 - 57.50 = $5, and this is 5/62.5 = 0.08 = 8% of the total cost of the filters when purchased individually.
