Number of cards they have 160 in the end.
Step-by-step explanation:
Given,
The ratio of cards David and Sam has = 4:5
Again,
David collected an additional 50% of cards.
Sam doubled his number of cards.
Sam now has 40 more cards than David
To find total number of cards they have.
Let,
David has 4x cards
Sam has 5x cards
Again,
Number of cards David has = 4x ×
= 6x
Number of cards Sam has = 5x×2 = 10x
According to the problem,
10x = 6x+40
or, 10x-6x = 40
or, 4x = 40
or, x = 10
Altogether they have = 6x+10x = 16x
= 16×10 = 160
Hence,
Number of cards they have 160 in the end.

Answer:
Each cupcake was $2.75
Step-by-step explanation:
We subtract the price of the ice cream from the total bill $22.26-$5.76=$16.50
We know he only bought the ice cream and cupcakes so once we subtracted the price of the ice cream, we now have the price of the cupcakes all together only
We divide the price of all the cupcakes by the amount of cupcakes to get the price of each individual cupcake $16.50/6=$2.75
Answer:
#1
Step-by-step explanation:
The associative property of addition states that we can "flip" two expressions that are being added. Therefore, our answer is the first one because it can be rewritten as 3x + (-7y) which then is equivalent to -7y + 3x.
