Answer:The width of the orange blanket is 23 inches.
Step-by-step explanation:
The total of both lengths is 75.We know that the green blanket is 52 so 75-52 = 23 which is the width of the orange blanket
The ratio is 5:12
Glad I help you
In one year
1 + (23/100) = (1 + x)^12
1 + 0.23 = (1 + x)^12
(1 + x)^12 = 1.23
1 + x = 1.23^(1/12)
x = 1.23^(1/12) - 1
x =~ 0.017400841772181508280113627030242
That's about 1.74% per month (which is about 20.881% per year), compounded monthly, to equal 23% per year, compounded annually.
So I believe you can write
<span>I=(1+.0174<span>)<span>12t</span></span></span>or<span><span>I=<span>1.0174<span>12t</span></span></span></span>
The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is
... 0.80 × $8750 = $7000
If x represents the amount invested at 7%, then the total interest earned is
... (7000 -x)×4% + (x)×7% = 420
... 280 +0.03x = 420
... x = 140/0.03 ≈ 4666.67
$4666.67 was invested at 7%.
$2333.33 was invested at 4%.
