Mrs Lee increased her savings by 25% to $517.
a;How much was her monthly savings before the increase?
b:How much more did she save?
a) Call the savings before the increase, S ....and we have
S + 25% S = 517
S + .25S = 517
1.25S = 517 divide by 1.25
S = 517 / 1.25 = $413.60
b) 517 - 413.60 = $103.40 more saved after increase
