Angie bought 44 pencils and paid 66.00. She sold the pencils at a rate of 2 for $3.50 calculate her profit.

Profit of $11.00

Step-by-step explanation:

44÷2=22

22×$3.50=$77

$77.00-$66.00=$11.00/profit

r and t.

both are 64 degrees.

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
