Flora Kenyon made a deposit of $1,600 to her savings account on July 1. For the next year she made no other deposits or withdraw
Drupady [299]

Answer:

A = $1,650.24

Step-by-step explanation:

A = P(1 + r/n)^nt

Where

A = future value

P = present value = $1,600

r = interest rate = 3.1% = 0.031

n = number of periods = 4

t = time = 1 year

A = P(1 + r/n)^nt

= 1,600( 1 + 0.031 / 4)^4*1

= 1600( 1 + 0.00775)^4

= 1600(1.00775)^4

= 1600(1.0314)

= 1,650.24

A = $1,650.24

Dominic, Ralf and Peter have just eaten a HUGE Christmas meal. Dominic now weighs half as much as Ralf, and Peter weighs three t
solong [7]
For the answer to the question above, \
Let
D = Dominic weight
R = Ralph weight
P = Peter weight

We have three unknowns so we should set up three equations. We do as follows:

D = 0.5R
P = 3D
D+R+P = 720

Solving simultaneously we obtain,

D = 120
R = 240
P = 360

<span>So the answer is 120 is the weight of Dominic</span>
