Question is confusing but 12/15 divides to 4/5 or rounds to 1
The weight of the cans is 19 oz and each box weighs 6 oz. The answer is D, 19n + 6 is the weight of a shipped box..
Answer:
c = 100, a = 50, s = 20
Step-by-step explanation:
following information is missing from the question
6c + 7a + 2s = 990
3c + 3a + 4s = 430
2c + 4a + 4s = 480
If you solve the equation by putting in the values given in the option you will deduce that only option d matches LHS to the RHS
Lets see how,
6c + 7a + 2s = 990
where, c = 100, a = 50, s = 20
6(100) + 7(50) + 2(20) = 990
600 + 750 + 40 = 990
990 = 990 hence true
2c + 4a + 4s = 480 where, c = 100, a = 50, s = 20
2 (100) + 4 ( 50) + 4 (20) = 480
200 + 250 + 80 = 480
See for the other option too with the same steps done above to have a more clear understanding :)
