Can someone please help me-
puteri [66]

Answer:

can be expressed as decimal: 0.025

s= 1.025* $250

 = $256.25

after 8 years

s= $250* 1.025^8

 ~$304.6

earned $54.6

Step-by-step explanation:

2 and a half is equivilant to 2.5

because it is a % (out of 100) move the decimal 2 places down

2.5-->0.25-->0.025

so can be expressed as decimal: 0.025

interest after 1 year is:

original amount of money * (interest rate+1.0)

+1 because you are adding on to 100%. you already have 100%.  if it was just the interest rate, the amount of money would go down.

so

s= 1.025* $250

=1.025* 250

=256.25

interest after 8 years,

that means you have to take the original, and multiply it by the interest rate, then the new original multiply by intrest rate a total of 8 times

to do this use an exponent, because exponents base the total off the total before them. if that makes any sense srry

s= $250* 1.025^8

 ~$304.6  (I used calculator)

to get her earnings, subtract the new amount of money with her original amount of money

304.6-250

=54.6

$54.6

hope this helps
