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? $

Step-by-step explanation:

since,

$p = \frac{i}{rt} \\$

i= 20

r=0.05

t=5

$p = \frac{20}{0.05(5)} \\$

$p = 80 \: answer$

300013182 The tax rate as a percent, r, charged on an item can be determined using the formula StartFraction c Over p EndFraction minus 1 equals r. – 1 = r, where c is the final cost of the item and p is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the item: c = p(1 + ). What is the final cost of a $40 item after an 8% tax is applied?

$

shretnuh c= 40(1+0.08). c= 43.2

300013182 Hallie can use the equation p = 4l + 4w + 4h to determine the sum of the lengths of the edges of a rectangular prism. She begins to solve the equation for h but runs out of time. Her partial work is shown below:

p = 4l + 4w + 4h
2. StartFraction p Over 4 EndFraction equals StartFraction 4 l plus 4 w plus 4 h Over 4.

300013182 3. StartFraction p Over 4 EndFraction equals l plus w plus h. = l + w + h
h = 4. h equals StartFraction p Over 4 EndFraction minus blank. –
Which expression should follow the subtraction in Hallie’s equation?

(l + w)
(l – w)
left-parenthesis StartFraction l plus w Over 4 right-parenthesis.
left-parenthesis StartFraction l plus w Over 4 EndFraction right-parenthesis.
