Question

The formula for the amount with simple interest is A = P(1 + rt). Find r, if A = 224, P = 200, and t = 2.

Answer 1

jst plug in the given values.
224=200(1+r*2)
224=200(1+2r)

Answer 2

ok then how do i get the r what should i do

Answer 3

224=200(1+2r)
224=200+400r
Pls follow the steps
1.Subtract 200 both sides
2.Divide by 400 both sides

Answer 4

r = 0.6

r = 0.12

r = 0.06

r = 0.012

Answer 5

r=0.12?

Answer 6

nope pls check again

Answer 7

r=0.6

Answer 8

A = P (1 + rt)
224 = 200 (1 + 2r)
224 = 200 + 400r
224 - 200 = 400r
24 = 400r
24/400 = r
.06 = r
