Question

Kenji has $600 to spend on exercise classes. Each weight training class(x) costs $20 and each aerobic class(y) costs $15. Write an inequality for this situation and determine which ordered pair is a solution to the inequality

Answer 1

20x + 15y <= 600

one solution is : (15,20)

Answer 2

thats not an answer choice

Answer 3

give me your answer choices

Answer 4

25,20
10,35
10,20
30,20

Answer 5

20x + 15y <= 600

(25,20)
20(25) + 15(20) <= 600
500 + 300 <= 600
800 <= 600 (not this one)

(10,35)
20x + 15y <= 600
20(10) +15(35) <= 600
200 + 525 <= 600
725 <= 600 (not this one)

(10,20)
20x + 15y <= 600
20(10) + 15(20) <= 600
200 + 300 <= 600
500 <= 600 (this one works)

(30,20)
20x + 15y <= 600
20(30) + 15(20) <= 600
600 + 300 <= 600
900 <= 600 (not gonna work

answer is : (10,20)
