Answer:
At 7% $54,000
At 9% $156,000
Step-by-step explanation:
Let x be the amount invested at 7%, Then 2x + 48000 will be the amount invested at 9%
We know that:
7% = 0.07 & 9% = 0.09
So we can write the interest equation as follows:
0.07x + 0.09 (2x + 48000) = 17820
0.07x + 0.18x + 4320 = 17820
0.25x + 4320 = 17820
Subtracting 4320 from both sides of the equation we get:
0.25x = 17820 - 4320
0.25x = 13500
Dividing both sides of the equation by 0.25 we get:
x = 13500 / 0.25
x = $54,000 invested at 7%
&
2 x 54000 + 48000
= $156,000 invested at 9%
Hence the amount invested at 7% is $54,000.
& the amount invested at 9% is $156,000.
Answer:
x=1 or 0
Step-by-step explanation:
because if X is 1 then 3*1 is 3 and 3+2 is five then it's bigger than -10 and smaller than 8
0*3 is 0 then 0 plus 2 is 2 which also works
Answer:the number of student tickets that were sold is 85
the number of adult tickets that were sold is 65
Step-by-step explanation:
Let x represent the number of student tickets that were sold.
Let represent the number of adult tickets that were sold.
MCHS sold 150 tickets at the last basketball game. This means that
x + y = 150
Student tickets cost $3 and adult tickets cost $5. If they sold $580 worth of tickets, it means that
3x + 5y = 580 - - - - - - - - - - -1
Substituting x = 150 - y into equation 1, it becomes
3(150 - y) + 5y = 580
450 - 3y + 5y = 580
- 3y + 5y = 580 - 450
2y = 130
y = 130/2 = 65
Substituting y = 65 into x = 150 - y, it becomes
x = 150 - 65 = 85
