Molemi o na le mae a a 900.  O a beile mo diterei,  terei nngwe le nngwe e tshokotsa mae a le 30.  Molemi o tla bona bokae fa a rekisa terie nngwe le nngwe ka $2.5?

Brenda invested $300 into a scheme that accumulates simple interest at the rate of three-quarters of the original amount per year. How much in total will she have after 3 years?
Go na le diterei di le 900 / 30 = <<900/30=30>>30 tse di tshwakgolang mae a a 900. 
Ka jalo he, molemi o tla bona $30 x $2.5 = $<<30*2.5=75>>75 fa a rekisa terie nngwe le nngwe.
#### 75 

Three-quarters of $300 is (3/4)*$300 = $<<(3/4)*300=225>>225
After 3 years, interest of $225*3 = $<<225*3=675>>675 has been accumulated
She now has a total of $300+$675 = $<<300+675=975>>975
#### 975
