Answer: $0.42
Pete can buy daffodil bulbs in packages of 3 for $8.31
OR
Pete can buy packages of 2 for $5.68
Firstly, we need to calculate the unit price to know the better price
Amount of buying one bulb of packages of 3 is
= 8.31 / 3
= $ 2.77
Amount of buying one bulb of packages of 2 is
= 5.68/2
= $ 2.84
The one with a better price is daffodil bulb with a packages of 3
If he buys 6 bulbs
The amount of selling one bulb in packages of 3 is $2.77
Buying 6 = 2.77 x 6
= $16.62
Buying 6 in packages of 2
= 2.84 x 6
= $17.04
$17.04 - $16.62 = $0.42
Therefore, Pete will be saving $0.42 when he is buying 6 bulmbs at a better price
