I’m not good with number lines. Please help.

Whole Numbers

Step-by-step explanation:

We can get the answer by looking at the number line. We see the blue dots above the numbers and as you can see there is no fractions or anything related. A whole number is like 1, 2 or 3. This gets our answer, whole numbers.

215.92 dollars is the answer

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
