If the simple interest on ​$1000 for 5 years is ​$250, then what is the interest​ rate?

Step-by-step explanation:

i=prt

250=(1000)((5)

250= 5000 r

250/5000 = r

r=0.05 or 5% internet rate

5%

Step-by-step explanation:

Interest earned=

PV-PV(1+it)

we have

250=1000-1000(1+5i)

solve for i

-750= -5000i

250= -5000i

.05= i

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
