⦁ A sum of $22,000 is invested in a savings account which pays interest at the rate of 7 percent per year compounded quarterly. If the amount is kept on deposit for 10 years, what will the compound amount equal? How much interest will be earned during the 10 Years

Compounded amount = $44,035.14

Interest earned =  $22,035.14

Step-by-step explanation:

Amount after t years = 22000(1 + 0.07/4)^4t

So after 10 years it is 22000(1 + 0.07/4)^40

= $44,035.14

and interest earned = $22,035.14

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
