1) $329.66

2) $8011.20

3) 3.2%

4) 4

Step-by-step explanation:

Simple interest formula: I = P*r*t

the simple interest on the loan: $875 at 6.85% for 5 years 6 months

5 years 6 months = 5,5 years

6.85% = 0.0685

I = 875*0.0685*5.5 = 329.66

the total amount due for the simple interest loan: $6400 at 5.3% for 4 years 9 months.

4 years 9 months = 4 + 9/12 = 4 + 0.75 = 4.75

5.3% = 0.053

I = 6400*0.053*4.75 = 1611.20

Total amount due: 6400+1611.20 = 8011.20

the interest rate on a loan charging $960 simple interest on a principal of $3750 after 8 years.

I = 960

P = 3750

t = 8

960 = 3750*r*8

960 = 30000*r

r = 0.032

r = 3.2%

the term of a loan of $350 at 4.5% if the simple interest is $63.

P = 350

r = 4.5% = 0.045

I = 63

t = ?

63 = 350*0.045*t

63 = 15.75*t

t = 4

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
