Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189
Answer:
<u>Option 4:</u> $2.18
Step-by-step explanation:
<u>Lets first analyse our given information. We know that:</u>
- Original Cost Per Jug: $0.80
- Mark Up cost: 150%
- Sales Tax: 9%
Now the Mark Up cost essentially means that the original price of any item has gone up (i.e. increased). So first let us find the Mark Up final cost of a $0.80 jug when price has increased by 150%, as follow:
Thus the jug after the mark up now costs $2.
Now lets compute the sales tax on the final jug cost, thus the 9% Tax on $2 as follow:
So finally the total cost of a jug of iced tea from A-1 Deli is $2.18 dollars (i.e. Option 4).
If you would like to know how far apart would Dale's house and school be on the map if the scale were 1 inch = 6 miles, you can calculate this using the following steps:
1 inch ... 8 miles
1 1/2 inches = 3/2 inches ... x miles = ?
1 * x = 8 * 3/2
x = 8 * 3/2
x = 12 miles
1 inch ... 6 miles
y inches = ? ... 12 miles
1 * 12 = 6 * y
12 = 6 * y /6
y = 12 / 6
y = 2 inches
The correct result would be C. 2 inches.
