Write a real-world situation that can be modeled by the inequality 20x > 30 + 15x.

20x > 30 + 15x.

John and Jack were making steel bars. John started earlier, and had already completed 30 steel bars by the time Jack clocked in for work. To make up the time, Jack created 5 more bars per hour then usual (usual being 15 bars an hour). How much hours are needed before Jack could surpass John?

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
