GenaCL600 [577]

Answer:

Rafael should buy 9 gift bags and 6 bows packet so, that she can have SAME NUMBER OF ITEMS, i.e 54.

Step-by-step explanation:

The gift bags are sold in the packs of 6.

So, the number of gift bags in 1 packet = 6 gift bags

The number of gift bags in 2 packet = 6 x 2 gift bags = 12 gift bags

The number of gift bags in 3 packet = 6 x 3 gift bags = 18 gift bags

And continuing similarly, we get

The number of gift bags in 9 packet = 6 x 9 gift bags = 54 gift bags.. (1)

The bows are sold in the pack of 9.

So, the number of bows in 1 packet = 9 bows

The number of bows in 2 packet = 9 x 2 bows = 18 bows

The number of bows in 3 packet = 9 x 3 bows = 27 bows

And continuing similarly, we get

The number of bows in 6 packet = 9 x 6 bows = 54 bows... (2)

Here, comparing both equations (1) and (2) , we get

The number of gift bags = 54 = The number of bows.

Hence, Rafael should buy 9 gift bags and 6 packet of bows so, that she can have SAME NUMBER OF ITEMS, i.e 54.
