I will appreciate some help on identifying the proper formula to handle a case such as the following:
- Let say we have a value (of 2000) and I will like to obtain the number to which when it is applied a 7% increase, it will sum 2000. Which is the formula to do this? Which is the mathematical name of this type of scenario?
Same as: what must 5 be multiplied by to give 30?
5 * m = 30
m = 30/5 = 6
What must 1.07 be multiplied by to give 2000?
1.07 * m = 2000
m = 2000/1.07 = 1869.15887....
If you're a "formula nut!", then:
A = original Amount (?)
D = Desired result (2000)
R = Rate (.07)
A = D / (1 + R)
or, if you prefer, make R the percentage (7%); then R = 7 and:
A = D / ( 1 + R/100)
