Find the amount of interest payable if $400 is borrowed at 14% interest and is to be repaid in 6 months

Shtirlitz [24]

Answer:

The amount of interest payable after 6 months is $28.

Step-by-step explanation:

Here, the Principal amount borrowed = $400

Rate of Interest = 14%

Time = 6 months = 6 / 12 years = 0.5 year

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

So, here SI = $SI = \frac{400 \times 14 \times 0.5}{100} = 28$

or, SI = $28

Hence, the amount of interest payable after 6 months is $28.

A parabola y=1/2x^2-4x+21 can you help me find the vertex form of this parabola please and thank you :)

ale4655 [162]

Ok
First factor out the first 2 terms as follows:-

y = 1/2(x^2 - 8x) + 21

Now complete the square on x^2 - 8x:-

y = 1/2[ (x - 4)^2 - 16] + 21

y = 1/2(x - 4)^2 - 8 + 21

y = 1/2(x - 4)^2 + 13 Answer

12 pack for $3.50

vlada-n [284]

The savings per unit between the best deal and worst deal is about $0.06

$\texttt{ }$

<h3>Further explanation</h3>

Let's learn about the basic formula about Profit and Loss

$\texttt{Profit = Selling Price - Cost Price}$

$\texttt{Selling Price = Cost Price ( 100\% + Profit\% )}$

$\texttt{Loss = Cost Price - Selling Price}$

$\texttt{Selling Price = Cost Price ( 100\% - Loss\% )}$

<em>Let us tackle the problem !</em>

$\texttt{ }$

<em>12 pack for $3.50 → 144 pack for </em> $\$ 3.50 \times \frac{144}{12} = \$ 42$

<em>24 pack for $6.00 → 144 pack for </em> $\$ 6.00 \times \frac{144}{24} = \$ 36$

<em>36 pack for $8.50 → 144 pack for </em> $\$ 8.50 \times \frac{144}{36} = \$ 34$

<em>48 pack for $11.75 → 144 pack for </em> $\$ 11.75 \times \frac{144}{48} = \$ 35.25$

$\texttt{ }$

<em>From information above, we can conclude that:</em>

The Best Deal → 36 pack for $8.50

The Worst Deal → 12 pack for $3.50

$\texttt{ }$

<em>The savings per unit between the best deal and worst deal :</em>

$( \$ 3.50 \div 12 ) - ( \$ 8.50 \div 36 ) = \$ (\frac{1}{18}) \approx \boxed {\$ 0.06}$
