In a game, players have 60 seconds to toss rings into boxes. Rings that land in green boxes, g, earn 5 points
Rings that land in blue boxes, b, earn 10 points
Players must earn at least 50 points to win
Which inequality models the combination of tosses needed to win?

g*5 + b*10 ≥ 50.

Step-by-step explanation:

Let's define g = number of rings that land in green boxes.

and b = number of rings that land in blue boxes.

For each ring in the green box you earn 5 points, then if there are g rings in the green box, you have g*5 points.

And for the blue is similar, if there are b rings in the blue box, you will have b*10 points.

Then the total number of points that you will get is:

T = g*5 + b*10.

And the minimum that you need to win is 50 points, the inequality will be:

T ≥ 50

or

g*5 + b*10 ≥ 50.
