Answer 2

Step-by-step explanation:

As we know that,

                    Principal + Simple Interest = Amount

So,

(a)  Given,

P = $9000 , Amount = $9800

∴ SI = Amount - P

       = $9800 - $9000

       = $800 (Ans)

(b) Given,

SI = $500 , Amount = $4900

∴ P = Amount - SI

     = $4900 - $500

     = $4400 (Ans)

(c) Given,

P = $6000 , SI = $250

∴ Amount = P + SI

                 = $6000 + $250

                 = $6250 (Ans)

(d) Given,

P = $1800, Amount = $2420

∴ SI = Amount - P

       = $2420 - $1800

       = $620 (Ans)

(e) Given,

SI = $340 , Amount = $4670

∴ P = Amount - SI

      = $4670 - $340

      = $4330 (Ans)
