Tahmar knows the formula for simple interest is I = Prt, where I represents the simple interest on an amount of money, P, for t

years at r rate. She transforms the equation to isolate P : P = P : P equals StartFraction I Over r t EndFraction.. Using this formula, what is the amount of money, P, that will generate $20 at a 5% interest rate over 5 years?

Answer:

$80

Step-by-step explanation:

Using the suggested formula, we can find the principal needed to generate the $20 interest at a 5% (in decimal form 0.05) interest rate over a period of 5 years:

P=\frac{I}{r*t} \\P=\frac{20}{0.05*5} \\P=\frac{20}{0.25}\\P=80

Therefore, she needs an $80 principal.

Serena is single. She purchased her principal residence three years ago. She lived in the home until she sold it at a $300,000 g
Lesechka [4]

Answer: Long -term capital gain

Step-by-step explanation:

Serena is single, so based on the Taxpayer Relief Act of 1997, she would pay no capital gains tax on the first $250,000 gain.

Therefore, $300,000 - $250,000 =  $50,000

<em>The remaining $50,000 gain is taxable because of her being single and it has been her principal residence for three years.</em>

To make a profit, a clothing store sells jeans at 115% the amount they paid for them. How much did the store pay for the jeans s
Svetllana [295]

Answer:

The store paid 6.67 times the profit made on the jeans

Step-by-step explanation:

Let the amount the clothing store pay for Jean be X

Let the amount the clothing store sells Jean be Y = X ×1.15

The profit (P) made is the difference between amount the clothing store sells Jean and the amount paid for Jean = Y - X = 1.15X - X

Profit (P)  = 0.15X

X =  P/0.15 = 6.67P

Therefore, the store paid 6.67 times the profit made on the jeans

At Billy's Burgers, two bacon cheeseburgers and three orders or curly fries would cost $ 16.45. One order of curly fries and thr
Mashcka [7]

Answer:

Curly fries=$2.29 per order

Bacon=$4.79 per order

Step-by-step explanation:

let b denote bacon and f denote curly fries.

We represent the situations  using inequalities as:

2b+3f=16.45\ \ \ \ \ ...i\\\\1f+3b=16.66\ \ \ \ \ ...ii

#we make f the subject of the formula in ii and substitute in i:

f=16.66-3b\\\\\#substitute \ in \ i\\\\2b+3f=16.45\\\\2b+3(16.66-3b)=16.45\\\\\\2b+49.98-9b=16.45\\\\-7b=-33.53\\\\b=4.79\\\\f=16.66-3\times 4.79\\\\=f=2.29

Hence, one order of curly fries costs $2.29 and one order of bacon costs $4.79

The graph shows two straight lines. The equation of line A is y = 2 - x Work out the equation of line B.
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

The equation of a line can be easily found from the graph.  First, find two points on the line that intersect points on the graph, then plot the changes in the two axis in this manner (change in y)/(change in x), or rise/run.  Thus, the slope of this line is 5/3.  Then, the  b in y = mx + b is simply when the line intersects the y-axis, in this case -5.  Thus, the equation of the line is

y = -5/3x - 5

Hope it helps <3
