This is exponential growth of the form
f=ir^t, f=final amount, i=initial amount, r=rate, t=time, in this case we know a=20 and r=2 so
f=20(2^t)
A) The amount of the discount is the interest due, $63.75.
I = Prt
I = 5000*0.051*13/52
I = 63.75
b) Zakir will pay the discounted price, $5000 -63.75 = $4936.25
c) The effective rate is r/(1 -rt) = 5.1%/(1 -0.051*13/52) ≈ 5.17%
Answer:
5:2
Step-by-step explanation:
divide then both my 3 to get 5 for 15 and 2 for 6
Answer: 9.1-10=0.2x
Step-by-step explanation:
9.1 = −0.2x + 10
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 −10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
10 = 9.1 + 0.2x
10 = 0.2x + 9.1
0.2x + 9.1 = 10
0.2x + 9.1 − 9.1 = 10 − 9.1
0.2x = 0.9
0.2x / 0.2 = 0.9 / 0.2
x=4.5
10 − 0.2x = 9.1
10 + (−0.2x) = 9.1
−0.2x + 10 = 9.1
−0.2x + 10 − 10 = 9.1 − 10
−0.2x = −0.9
−0.2x / −0.2 = −0.9 / −0.2
x=4.5
9.1 - 10 = 0.2x
-0.9 = 0.2x
-0.9 / 0.2 = 0.2x / 0.2
x= -4.5
