20

-20

0

x ≥ $15

Step-by-step explanation:

At least means ≥

4x ≥ $60     Replace the inequality sign with an = sign and solve the equation.

4x = $60

x  = $60 ÷ 4

x = $15                 Now put the inequality sign back into the problem

 x ≥ $15

no i do not : ( what is it?

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:
