A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller) The picture below shows a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image. The image always has a prime after the letter such as A'.
A 15-minute shower a day costs about $310 a year, even with a low-flow shower head. Cutting the time by a third will save about $100 annually. Buy torn bags of mulch. Home centers usually set these torn bags aside, then sell the dayâs mishaps at a big discount.
Use your overhead costs to guide you. For example, if you sell a meal for $12 and have an $8 overhead cost, your food costs must be no more than $4 to break even. If you want a profit of $2 per plate, your sales price would then need to be $14, giving you a food-cost percentage of about 29 percent.or example, if your overhead is $2,000 per day and you serve 250 customers daily, your overhead cost per person is $8. Include allowances for employee meals and food theft in the overhead figure, since these are not direct costs to serve a customer meal.
