Given:
Total amount invested = $9,000
interest rates = 4% and 6%
Let x be the part of 9,000.
Note that annual return on each investment is the same.
0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400
0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216
total interest for the year : 216 + 216 = 432
Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate
Interest rate would be 4.8% to get the same interest from the whole 9,000.
The expression would be
1/2h + 1
1 large drink cost $1.65
Work: 16.95 - 12.00 = 4.95 <- Cost of drinks
Then 4.95 divided by 3 = 1.65
So it is $1.65 per large drink.
Hope I was able to help!
Answer:
The mean is 9.5 and the median is 6.5.
Step-by-step explanation:
<em>To find the mean:</em>
Add all numbers given.
9+8+5+3+37+8+4+2= 76
Then divide by the amount of numbers (8).
76/8= 9.5
<em>To find the median:</em>
Re-arrange the order of the numbers from least to greatest.
2, 3, 4, 5, 8, 8, 9, 37
Count towards the middle. If there is no exact middle (like this equation), then take the two middle numbers and add them.
5+8= 13
After, divide by two since there are two numbers being added.
13/2= 6.5
