Daisy is arranging for a party. She wants to buy 11 packs of balloons for her party. The price is $7.50 and the sale price is $4.35. But, instead of buying 11 packs,she buys 5 packs of balloons. How much did it cost?
Easy
If Daisy buys 11 packs of balloons at the sale price of $4.35 each, then the total cost would be 11 x $4.35 = $47.85.
But she only buys 5 packs of balloons, so the total cost would be 5 x $4.35 = $21.75.
Therefore, it would cost Daisy $21.75 to buy 5 packs of balloons instead of 11.
