Answer: $900
Step-by-step explanation:
The simple interest is calculated using the formula:
(P × R × T)/100
where,
P = Principal = $3000
R = Rate = 6%
T = Time = 5 years
Simple Interest = (P × R × T)/100
= ($3000 × 6 × 5)/100
= 90000/100
= $900
Therefore, the simple interest is $900
2) 0= n
3 X= -7
5 no Solution
6 p=1
Let's represent that number as X:
6(9+2X) = 5X + 12
54 + 12X = 5X + 12
7X = -42
X = -6
To find the difference, subtract Thea's earnings from Hadley's earnings.

Thea earned $54 more than Hadley.
Answer:
89.008
Step-by-step explanation:
z = (x– mean)/ standard deviation
x = z * standard deviation + mean
Now, z value for the top 4% of the exams (which is the same as getting a score below the 96%) has to be found using a z table.
In this case z = 1.751
x = 1.751 * 8 + 75
x = 89.008
