8. John buys a TV for $1900. He later sells it for
Semmy [17]

John bought the TV for . . . . $1,900

John sold the TV for . . . . . $750

John lost this much on the TV . . . (1,900 - 750) = $1,150

What fraction of the amount he paid did he lose ?

$1,150 / $1,900 = 0.6053 of the amount he paid never came back

What is this fraction as a percentage ?

0.6053 = 60.53 %

Rounded to one decimal place:  <em>60.5 %  </em>

John took a beating on that TV.  I hope he got a lot of good use out of it while he had it.

You deposit $870 into a savings account that pays 3.7% interest compounded
makkiz [27]

Answer:

$970. 19

Step-by-step explanation:

Using the compound interest formula Accrued Amount = P (1 + r)^t

where Accrued amount is to be determined

P = principal; $870

r = 3.7% = 0.037

t = number of years = 3

Therefore

Accrued amount = 870 (1 + 0.037)^3

Accrued amount = 870 x 1.037^3

= 870 x 1.1152

= 970. 19

Hence balance of the account at the end of 3 years is $970. 19
