Given that 8 oz of Lots of suds cost = $0.98
Then unit price of 1 lot of suds = 0.98/8 = $0.1225
Given that 12 oz of Bright wash cost = $1.29
Then unit price of 1 Bright wash = 1.29/12 = $0.1075
Given that 30 oz of Spotless soap cost = $3.14
Then unit price of 1 Spotless soap = 3.14/30 = $0.104666666667
Given that 32 oz of Lemon bright cost = $3.50
Then unit price of 1 Lemon bright = 3.50/32 = $0.109375
We also need to round the values to the nearest thousandth means three digits after decimal
Then unit price of 1 lot of suds = $0.123
unit price of 1 Bright wash = $0.108
unit price of 1 Spotless soap = $0.105
unit price of 1 Lemon bright = $0.109
Now we can easily sort them
0.105 < 0.108 < 0.109 < 0.123
respective names in sorted order are:
Spotless soap < Bright wash < Lemon bright < lot of suds
Hence final answer is :
Spotless soap < Bright wash < Lemon bright < lot of suds
