Show work and you! a sporting goods store marks up the cost s of soccer balls by 250%. write an expression that represents the retail cost of the soccer balls. the store buys soccer balls for $5.00 each. what is the retail price of the soccer balls

new price = cost + cost* percentage increase

250 percent = 2.5 as a decimal ( 250% = 250/100 = 2.5)

new price = cost + cost * 2.5

factor out cost

new price = cost(1+2.5)

new price = cost(3.5)

substitute the retail price (or cost)

new price = 5(3.5)

new price = 17.5

I am assuming the retail price is the selling price or the new price

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
