Answer:

x/50 = 40/100

x = 20

Step-by-step explanation:

It is useful to remember that the symbol % is a shorthand way to write /100. (Similarly, the symbol ‰ is a shorthand way to write /1000.) This means the number 40% represents the ratio 40/100. In decimal, that is 0.40 (forty hundredths).

When this is the fraction that represents the number of test questions that are correct, you can see that the proportion should be ...

correct / total questions = x / 50 = 40 / 100 . . . . the desired proportion

Multiplying by 50 gives the value of x:

x = 50(0.40)

x = 20 . . . . the value of x

Suzanne is looking at taking out a personal loan. Opportunity Loans is offering her $1600 at 3.45% for 1 year, with interest com

AleksAgata [21]

Step-by-step explanation:

So the general formula for compound interest is $A = P(1+\frac{r}{n})^{nt}$ where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get

Opportunity Loans:

$A = 1600(1+\frac{0.0345}{12})^{(12)(1)}$

$A = 1600(1.002875)^{12}$

$A \approx 1600(1.035)$

$A = \$1,656.08$

Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

$Interest=1656.08-1600\\Interest=56.08$

General Loans:

$A = 1600(1+\frac{0.042}{4})^{(4)(1)}$

$A = 1600(1.0105)^4$

$A \approx 1600(1.042)$

$A = 1,668.27$

To find the interest we do the same thing we did in the previous problem

$interest = 1668.27-1600\\interest=68.27$

Opportunity loans has the least amount of interest after a year
