Selene buys two instant cameras at $110 and three digital photo frames at $120 each. She gets a 5% discount on all the items she purchased. How much does she pay in all?
Think hard. Detailed solution:
551
Two instant camera cost 2 x $110 = $220.

Three digital photo frames cost 3 x $120 = $360.

Thus, the total amount is $220 + $360 = $580.

So, Selena gets a discount of 5 / 100 x 580 = $29.

Therefore, Selena pays a total of $580 - $29 = $551.
