Your total expenses: $1,725 divided by 4 children = $431 per month per child, or 19.59 per day based on 22 working days. Now you can see that from your base rate of $19.59 per day, you have room to work within the costs charged in your local area and still make a profit.or example, if you plan to work a 50 hour week, you need to multiply that by say, $10 per hour for a total of $500 per week. Finally, divide that total by the number of children you plan to care for, ($500 divided by 4 children =$125 per child per week).
1. a measure of cardiac pump performance, the degree to which muscle fibers can shorten when activated by a stimulus independent of preload and afterload. The definition information for cardiac contractility is provided by Stedman's.
It doesn't - contractility refers to the force generated at any given length of muscle. Therefore although the force of contraction does increase with filling, the contracti â¦ lity does not. The reason the force of contraction increases with filling is because filling stretches the heart muscles. Increased stretch causes an increase in force of contraction. Contractility changes because of changes in the level of intracellular calcium.
