Write an inequality

Question

Kris is saving for a $300 bike.He already has $50 saved and adds $10 every week to his savings.

Answer 1

I'm assuming you want to know how many weeks it will take for him to buy his bike.

Let W = Weeks saved

300 <= 50 + 10*W

250 <= 10* W

25 <= W

He'll be able to buy his bike anytime after the 25th week.

------------------------------

Always check your answer,

50 + 10*25 = 300

300 = 300

correct

Answer 2

Hi, This is Frank. The answer is an inequality based on linear equation in the form of: y</=ax+b in which y is the value of the bike($300), x is the no. of weeks, a and b are constants a=$10 and b=$50, therefore the inequality is: 300</= 10 x+50. Subtracting 50 from both sides: 250</= 10 x, or x>/=25.
