Answer:

\boxed{x=7 }

Step-by-step explanation:

3x - 11 = x + 3

→ Minus x from both sides to isolate the 'x's

2x - 11 = 3

→ Add 11 to both sides to isolate 2x

2x = 14

→ Divide both sides 2 to isolate x

x = 7

Create a proportion using the form %/100 = is/of to represent the following word problem. 15 is 1 1/2% of what number?
Tema [17]
Let the required number be x, then to create a proportion using the form
\frac{\%}{100} = \frac{is}{of}

Thus, let 15 be 1 \frac{1}{2} \% of x, then
\frac{1 \frac{1}{2}}{100} = \frac{15}{x}  \\  \\  \frac{ \frac{3}{2} }{100} =\frac{15}{x} \\  \\ \frac{3}{2}x=1,500 \\  \\ x= \frac{1,500\times2}{3} =1,000

Therefore, 15 is <span>1 \frac{1}{2} \% of</span> 1,000

You take out $50,000 for loans during your college career. You must pay it back with 7% APR for 20 years, making monthly payment
Ad libitum [116K]

Answer:

The monthly payment for the loan amount for 20 years is $806.167

Step-by-step explanation:

The principal loan amount= $ 50,000

The rate of interest = 7 %

the time period of loan = 20 years = 20 × 12 = 240 months

let the amount after 20 years = $ A

<u>From Compounded method</u>

Amount = Principal × (1+\dfrac{\textrm rate}{100})^{\textrm Time}

or, A = 50,000 × (1+\dfrac{\textrm 7}{100})^{\textrm 20}

or, A = 50,000 × (1.07)^{20}

Or, A = 50,000 × 3.8696

∴ Amount = $ 193,480

So, The amount after 20 years = $ 193,480

The monthly payment amount = $ \frac{193480}{240} = $ 806.167

Hence The monthly payment for the loan amount for 20 years is $806.167 Answer
