In League of Legends, a player’s Effective Health when defending against physical damage is given by: . Where H ins health and A is armor. Health costs 2.5 per unit and Armor costs 18 gold per unit. Ten minutes into the game, you have 1080 health and 10 armor. You have only 720 gold to spend, and the health armor costs the same as before. Again, the goal is to maximize the effectiveness E. Notice that you don’t want to maximize the effectiveness of what you purchased - you want to maximize the effectiveness

E of your resulting health and armor. How much of each should you buy?

Part B:
Thirty minutes into the game, you have 2000 health and 50 armor. You have 1800 gold to spend, and
again the costs are the same. You once more want to maximize the effectiveness E of your resulting health
and armor. How much of each should you buy?

hello!

to begin with, we're given that on earth, a rock weighs 20 pounds, and while on jupiter, that same rock weighs 42 pounds. now, we're trying to find the weight of a rock that weighs 10.5 pounds on earth, on jupiter.

to solve this, first, set up a proportion, cross-multiply, and solve it algebraically.

setting up the proportion is the hardest and the most confusing part of the problem, but it's simple.

if on earth, the rock weighs 20 lbs, and on jupiter it weighs 42 lbs, our first part of our proportion is 20/42 lbs. the second part has to be equal to each other. this means that 10.5 has to be on the numerator of the fraction, and x, the value we're trying to find, has to be on the denominator. remember that the rock weighs 10.5 lbs on earth, and we're trying to find the weight of it on jupiter (which is x).

20/42 = 10.5/x

next, you would cross-multiply.

20x = 42(10.5)

20x = 441

now, solve it algebraically by using division.

x = 22.05 lbs

this can be rounded to 22.1 lbs.

therefore, the weight of the rock on jupiter is 22.1 lbs, the fourth choice.
