A house on the market was valued at $327,000. after several years the value increased by 17% by how much did the house's value increase in dollars? what is the current value of the house?
How much did the house's value increase in dollars?
327,000 x 0.17 (17%) = $55,590
What is the current value of the house?
327,000 + 55,590 = $382,590
We are told that the principle is the same for both investments so we can say:
315=P(r+4)/100 and 175=Pr/100 solving both for P you have:
P=31500/(r+4) and P=17500/r since P=P:
17500/r=31500/(r+4)
175(r+4)=315r
175r+700=315r
-140r+700=0
-140r=-700
r=5
So the rates are 5% and (5+4)=9%
check...
P(9/100)=315 and P(5/100)=175
P=31500/9 and P=17500/5
P=157500/45 and P=157500/45
So P=P
note: P=$3500
3500(9/100)=$315
3500(5/100)=$175
Subtract 6x from 9x
-15=3x-6
add 6 to both sides
-9=3x
divide 3 from both sides and -3=x
Answer:
Marked up Price = $61.80
Step-by-step explanation:
we are given that The wholesale price of a flower arrangement was $60 and the flowers were marked up 30%.
Hence Marked price = increased price + Wholesale price
Increased price = 30% of whole sale price
= 0.30 x $60
=$1.8
Marked up Price = $1.8+$60
= $61.80
