Answer:
The total number of 50 cent coins in the bag = 36.
Step-by-step explanation:
Let x be the number of 50 cents coins and y be the number of $1 bills.
We have been given that the total amount of money in the bag is $36. We can represent this information as:
We are also told that there are twice as many 50 cents coins as $1 bills. We can represent this information as:
Now we will use substitution method to solve our given system of equations. Upon substituting equation (2) in equation (1) we will get,
Now let us substitute y=18 in equation (2) to find our x.
Therefore, there are 36 fifty cent coins in the bag.
