Jawab:

a) Andrew deposited $3000 in the bank at the beginning of the year.

b) The amount of interest he earned was $45. The interest rate in that bank is 1.5% per year.

Penjelasan dengan langkah-langkah:

The amount of Andrew's money in the bank at the end of one year is 101.5% of the amount of money he deposited at the beginning of the year:

$3045 = 101.5% × m

(m = the amount of money Andrew deposited at the beginning of the year)

$3045 = 101.5% × m

m = $3045 ÷ 101.5%

   = $3045 ÷ (101.5/100)

   = $3045 × 100/101.5

   = $3000

∴ Therefore, Andrew deposited $3000 in the bank at the beginning of the year.

The amount of interest he earned:

$3045 – $3000 = $45

Because this is the amount of interest in one year, we can say that the interest rate in that bank is 1.5% per year.
