6% of a + 10% of (9000 - a) = 790
a = 2750
(9000 - a) = 6250
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.
<h3>What is a percentage?</h3>
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total amount = $9000
Let the part invested for 6% = a
Let the part invested for 10% = (9000 - a)
Now,
6% of a + 10% of (9000 - a) = 790
6% = 6/100 = 0.06
10% = 0.1
0.06a + 0.1(9000 - a) = 790
0.06a + 900 - 0.1a = 790
-0.04a = 790 - 900
0.04a = 110
a = 110/0.04
a = 2750
Now,
9000 - a = 9000 - 2750 = 6250
Thus,
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.

is it a exam question?
Answer:
187.5
Step-by-step explanation:
6% of 3125
=> 6/100 x 3125
=> 18750/100
=> 187.5
Equation 1 for tickets sold:
$35x + $25y = $10,250
Equation 2 for quantity (number #) of tickets sold:
x + y = 350
Use substitution method:
y = 350 - x
35x + 25 (350 - x) = $10,250
35x + $8750 - 25x = $10,250
10x + $8750 = $10,250
- $8,750 -$8,750
10x = 1,500
x = 150
y = 350 - 150
y = 200
Check the answers:
$35 (150) + $25 (200) =
$5,250 + $5,000 = $10,250
