Compound interest is interest earned or paid on both the initial investment and previously earned interest. It is an application of exponential growth.
Compound Interest formula
A=P(1+
P=principal or starting amount 14,000
n=number of times interest is compounded (if monthly, n=12)
r=rate convert % to decimal divide by 100 or move decimal.
t=time 10 years
Maria's parents invested $14,000 at 6% per year compounded monthly. How much money will
there be in the account after 10 years?
Use a calculator to complete this problem after finding the rate and time
A=14,000(1+rate)12 x time
12

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
