Some calculators label this (-) , some with +/- . The switch can be nearby the = key or the point that is decimal.
In case the calculator shows operations upon it (typically a calculator with multiline display), to calculate 1.005 -240 youвЂ™d type something such as: 1.005 ^ (-) 240
Then usually you hit the (-) key after a number to negate it, so youвЂ™d hit: 1.005 yx 240 (-) = if your calculator only shows one value at a time,

r = 0.04 4% yearly price
k = 1 since weвЂ™re doing scholarships that are annual
P0 = 100,000 weвЂ™re you start with $100,000
Solving for d gives $7,358.18 Each that they can give in scholarships year.
It’s well worth noting that always donors alternatively specify that only interest is to be utilized for scholarship, helping to make the initial contribution final indefinitely. If this donor had specified that, $100,000(0.04) = $4,000 a 12 months could have been available.
