Samantha asked for a loan from the bank of 4,500 plans to repay it in 4 years Samantha will have to repay it 900 of interest what is the simple interest rate

5

Step-by-step explanation:

S.I is defined mathematically as

[P x R xT]/100

P -Principal amount borrowed

R- the rate

T -time duration

S.I -simple interest [in this case 900]

S.I =[4500 x R x 4]/100

900 =[4500 x R x 4]/100

900x100 = 4500 x 4 x R

[900 x 100]/[4500 x 4] = R [by changing the subject of the formula to reflect R on the right side; you divide both sides by 4500 x 4]

90000/18000 =5

5=R

Rate =5%
