Question

What is the rate if the principal is $550, the time is 3 years, and the interest is $57.75 and how?

Answer 1

i believe its dookey.

Answer 2

haha very funny

Answer 3

I just answered your question @lataesiaaa

Answer 4

what???

Answer 5

its dookey with a side of eyeballs

Answer 6

really
this is not funny I need help

Answer 7

What is the formula to find out the interest ?

Answer 8

I= p(principal) x r(rate) x t(time)

Answer 9

\(I = p *r* t\), then to find \(r\), you need divide both sides by \(p*t\)
Now, what do you get?

Answer 10

3.5%

Answer 11

\(r =\dfrac{I}{p*t}\)
your \(I= 57.5\\p=550\\t=3\)
nothing is hard, right?

Answer 12

nope

Answer 13

hahaha.. ok, so it is hard to me

Answer 14

yeah oh and it's 57.75 for interest

Answer 15

ok

Answer 16

so I did it differently

Answer 17

\(I = prt\)

\(prt = I\)

\(r = \dfrac{I}{pt} \)

\(r = \dfrac{$57.75}{$550 \times 3} \)

\(r = \dfrac{57.75}{1650} \)

\(r = 0.035\)

\(r = 3.5\%\)
