Rate of appreciation is based on an exponential function, i.e.
if r=rate of appreciation, after n years, the new value is
F=P(1+r)^n.
P=present worth
F=future worth.
Here,
P=126000
F=156000
n=8
so
156000=126000(1+r)^8
=>
(1+r)^8=(156000/126000)=26/21
=>
(1+r)=(26/21)^(1/8)=1.02706 (approx.)
=>
r=1.02706-1=0.02706, or
rate of appreciation is approximately 2.7%
Your answer is 3/5b + 79.50 = 132.50.
3/5b +79.50 = what - like an algebra question solve for b.
3/5b +79.50 = -79.50
- 79.50
3/5b = 79.50
5/3 x 3/5 b = 79.50 x 5/3
b - 79.50/1 x 5/3 = 397.50/3
b = 132.50
5+4b<span>≥32
7 Packages of bracelets.
Solve It
5+4b</span><span>≥32
subtract 5 from both sides
4b</span><span>≥27
divide 4 on both sides
b</span><span>≥6.75
Since you can't buy a half packet you round up to 7</span>
Answer:
addition
Step-by-step explanation:
32(d/2 - 5) = 224
divide both side by 32
d/2 - 5 = 224/32
d/4 - 5 = 7
multiply both sides by 4
d - 20 = 28
lastly, add 20 to both sides
d = 28 + 20
d = 48
therefore, the last step is addition
