II. Write an equation for these problem then solve for the
1. A bag worth P1000 was sold with a 20%
discount, how much was the discount?
2. Richard got 16 in a 20 item test. What percent
of the test did he answer correctly?
3. Chito has P20 in his pocket, which is only 5%
of the money of her sister. How much is her
sister's money?
4.In a survey, 18 teenagers prefer dancing than
singing. If this represented 60% of the
respondents, how many respondents were there
in all?
5.A painter can finish painting a house in 30
days. If he has been painting for 24 days, what
percent of the painting job has not completed

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

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
