Randall starts a business collecting and selling baseball cards. he purchases 3 packs of cards for $3.75 each. each pack includes 12 cards. if he sells each card for $1.25, how much money will randall earn from sells?

Randall earned $33.75 from selling baseball cards.

Step-by-step explanation:

Given:

Cost for each pack of card = $3.75

Number of packs = 3

Hence Cost of 3 packs of card can be calculated by multiplying Cost for each pack of card with number of packs

Cost of 3 packs of card =

Also Given:

Each pack contains = 12 cards

3 pack contains = number of cards in 3 pack

By using Unitary method we get;

Number of Card in 3 pack =

Hence Purchasing Price of 36 cards = $11.25

Now Given that;

Selling price for each cards = $1.25

Selling price for 36 cards = price for 36 cards

By Using Unitary method we get;

Selling price for 36 cards =

Now Money Earned can be calculated by subtracting Purchasing Price with selling price we get;

Total Money earned =

Hence Randall earned $33.75 from selling baseball cards.

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
