You look at the point at which the graph lines meet and that is how you find you constant of proportionally.
Answer:
Emily=24 marbles Zak=8 marbles
Step-by-step explanation:
sum of ratio= 3+1=4
Emily: Zak= 3:1
no. of marbles for Emily= 
×total no. of marbles
= 
×32
=24 marbles
No. of marbles for Zak= 
×32
=8 marbles
<span>You trade in and rebate amounts reduced the price you have to finance, while the sales tax added to the amount to be financed.
Cost+1248 Sales Tax= Amount needed to be paid
- 2000 Rebate-5000 Trade in=
22048 Amount to be financed
Cost+1248-2000-5000=22048
Cost-5752=22048=27800</span>
Answer:
2441.95 years
Step-by-step explanation:
We can model this exponencial function as:
P = Po * (1+r)^(t/n)
Where P is the final value, Po is the inicial value, r is the rate, t is the time and n is the period of half-life.
In this case, we have that P/Po = 100% - 25.5% = 74.5% = 0.745, r = -0.5 and n = 5750, so we have that:
0.745 = (1 - 0.5)^(t/5750)
Step 1: log in both sides:
log(0.745) = (t/5750) * log(0.5)
Step 2: isolate t
t = 5750*log(0.745)/log(0.5) = 2441.95 years
