A jar of jelly bean candies weighs 8 ounces. A container of caramel candies weighs 40 ounces. Lúcia buys 10 pounds worth of jelly bean candy jars and caramel candy containers for her big party. Given that there are 16 ounces in a pound, which of the following equations correctly relates the number of jars of jelly bean candies, 
j, and the number of containers of caramel candies, 
c, that Lúcia bought?
Choose 1 answer:
(A) 
(8)/(16)j+(40)/(16)c=10
(B) 
8j+40 c=10
(C) 
(16)/(8)j+(16)/(40)c=10
(D) 
16*8j+16*40 c=10

Q. A jar of jelly bean candies weighs 88 ounces. A container of caramel candies weighs 4040 ounces. L\'ucia buys 1010 pounds worth of jelly bean candy jars and caramel candy containers for her big party. Given that there are 1616 ounces in a pound, which of the following equations correctly relates the number of jars of jelly bean candies, jj, and the number of containers of caramel candies, cc, that L\'ucia bought?\newlineChoose 11 answer:\newline(A) 816j+4016c=10\frac{8}{16}j+\frac{40}{16}c=10\newline(B) 8j+40c=108j+40c=10\newline(C) 168j+1640c=10\frac{16}{8}j+\frac{16}{40}c=10\newline(D) 168j+1640c=1016\cdot 8j+16\cdot 40c=10
  1. Convert to ounces: Convert the total weight Lúcia bought from pounds to ounces.\newlineLúcia bought 1010 pounds of candy. There are 1616 ounces in a pound, so the total weight in ounces is:\newline1010 pounds ×\times 1616 ounces/pound == 160160 ounces.
  2. Equation setup: Set up the equation to represent the total weight of the candies in terms of the number of jars and containers.\newlineThe weight of jj jars of jelly bean candies is 88 ounces per jar, so the total weight for the jelly beans is 8j8j ounces.\newlineThe weight of cc containers of caramel candies is 4040 ounces per container, so the total weight for the caramels is 40c40c ounces.\newlineThe total weight of the candies is the sum of the weights of the jelly beans and caramels, which equals 160160 ounces (from Step 11).\newlineSo, the equation is 8j+40c=1608j + 40c = 160.
  3. Simplify equation: Simplify the equation if necessary.\newlineThe equation 8j+40c=1608j + 40c = 160 can be divided by 88 to simplify it:\newline(8j+40c)/8=160/8(8j + 40c) / 8 = 160 / 8\newlinej+5c=20j + 5c = 20\newlineHowever, this simplified equation is not one of the answer choices, so we need to check the original equation against the answer choices.
  4. Compare with choices: Compare the original equation to the answer choices.\newlineThe original equation from Step 22 is 8j+40c=1608j + 40c = 160. Let's compare this to the answer choices:\newline(A) (8/16)j+(40/16)c=10(8/16)j + (40/16)c = 10 simplifies to 0.5j+2.5c=100.5j + 2.5c = 10, which is not equivalent to our equation.\newline(B) 8j+40c=108j + 40c = 10 is not correct because it does not account for the total weight of 160160 ounces.\newline(C) (16/8)j+(16/40)c=10(16/8)j + (16/40)c = 10 simplifies to 2j+0.4c=102j + 0.4c = 10, which is not equivalent to our equation.\newline(D) 168j+1640c=1016*8j + 16*40c = 10 is not correct because it would greatly exceed the total weight of 160160 ounces.\newlineNone of the answer choices match our equation, which suggests there might be a mistake in the problem or the answer choices provided.
