Answer:
the interest earned= 93.401
and the future value of an annuity= 493.401
Step-by-step explanation:
Given Data:
Interest rate= 7%
time,t = 3 years
weekly payment, P= 400
At the end of 3 years, final investment A= ?
n= 52 as it is weekly
As per the interest formula
A= P(1+r/n)^nt
Putting value in above equation
= 
= 493.401
Interest earned = A-P
= 493.401-400
= 93.401 !

Answer:
Dimensions are 8 Inches by 14 inches by 20 inches
Step-by-step explanation:
The volume of the box is 2240. This means:
lbh = 2240
Where b is the width.
Width is two inches less than twice the height
b = 2h - 2
length is 4 inches less than 3 times the height
l = 3h - 4
Substituting these parameters into the lbh equation will yield the following:
h * (3h - 4) * (2h - 2) = 2240
h[6h^2-14h+8] = 2240
6h^3 -14h^2 + 8h - 2240= 0
Solving this cubic equation will yield one of the values to be 8. The other two values are complex numbers.
b = 2h - 2
l = 3h - 4
b = 2(8) - 2 = 14
l = 3(8) - 4 = 20
The answer would be B
