Algebraically manipulating the formula I = Prt, find the principal (PV) deposited in a savings account which earned $11,000 in interest at a simple interest rate of 9.5% for 15 years to the nearest whole cent).

$7,312.07
$8,083.92
$7.719.30
$6,987.44
None of these choices are correct.

the required principal value is $7,719.30

Step-by-step explanation:

Given: Formula to calculate interest : I= Prt, P=principal value, r = rate of interest, t = time.

I = $11,000

r= 9.5% = 0.095

t= 15 years

Substitute in formula, we get

Hence, the required principal value is $7,719.30

i belive those are the ones that are under 90 degreese.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
