Answer:

$42

Step-by-step explanation:

Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.

According to the given information:

Amount received by Amjit = Amount received by James + 28

So,

6x = 4x + 28

6x - 4x = 28

2x = 28

x = 28/2

x = 14

Amount of money received by Penny = 3x = 3*14 = $42

Anna71 [15]

Answer:

Step-by-step explanation:

Out of all of the answers provided, H seems like the equation that makes the most sense.

$(60 * 3) = 180$

$[480 - (180)] = 300$

$300 = 60$

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

$300 / 60 = 5$

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.

From that, H would be considered the best equation that Mr. Hanson would use.
