An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working.

Two liquids can form different types of emulsions

In finance, the rule of 72, the rule of 70[1] and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling. Although scientific calculators and spreadsheet programs have functions to find the accurate doubling time, the rules are useful for mental calculations and when only a basic calculator is available.[2]

These rules apply to exponential growth and are therefore used for compound interest as opposed to simple interest calculations. They can also be used for decay to obtain a halving time. The choice of number is mostly a matter of preference: 69 is more accurate for continuous compounding, while 72 works well in common interest situations and is more easily divisible. There are a number of variations to the rules that improve accuracy.

Business practices
Many items are priced at $1.00 or less, and initially almost all items were priced as such.[12] In early 2009, Dollarama began to introduce items priced up to $2.00 (including $1.25 and $1.50 price points). Due to the positive response from consumers to the multi-price point strategy, the stores subsequently introduced items at $2.50 and $3.00 in August 2012. They again increased price points to include $3.50 and $4.00 items in August 2016. This price level increase allowed the chain to acquire products from a greater variety of sources, including closeout sales.[18] Adjustments may eventually happen to all prices.[19] Dollarama has always had a No Return and No Exchange Policy. Once an item is checkout/ bought, it cannot be returned or exchanged.
