Linda sold t-shirts at a festival. She made $5 for each t-shirt she sold. Her expenses were $22. If she made a profit of $83, how many t-shirts did she sell?

she sold 21 teeshirts

Step-by-step explanation:

y=5x -22 is the equation for the cost of the  tee shirts for her (22) and the cost for others(5x bc we dont know the amount shes sold yet).

if she made 85 dollers in profit shehad already paid off the 22 dollars it cost.

So you would add 22+83. which would equal 105.  then divide 105 by 5 for the number of tee shirts she sold. 105/5 =21

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
