his money into his piggy bank.
His piggy bank contains $70 and has only $5 bills
and $10 bills. He also knows he has 11 total bills in
the bank.
How many of each type of bill does André have in
the bank?
Answer:
André has 8 $5 bills in his piggy bank
Step-by-step explanation:
Let's call the number of $5 bills in André's piggy bank "x" and the number of $10 bills "y."
From the information given, we can create two equations to represent the situation:
André's weekly allowance: $5 per week.
Money earned for mowing the neighbor's yard: $10 per time.
André's total earnings can be represented by the equation:
Total Earnings = 5x (from allowance) + 10y (from mowing the yard)
We also know that the total amount in the piggy bank is $70:
Total Amount = 5x (from $5 bills) + 10y (from $10 bills)
We're also told that André has a total of 11 bills in his piggy bank:
Total Bills = x (number of $5 bills) + y (number of $10 bills) = 11
Now we have a system of two equations with two variables:
5x + 10y = 70
x + y = 11
We can solve this system of equations using substitution or elimination. Let's use the elimination method. First, we can multiply the second equation by 5 to make it easier to eliminate one of the variables:
5x + 10y = 70
5x + 5y = 55
Now, subtract the second equation from the first equation to eliminate x:
(5x + 10y) - (5x + 5y) = 70 - 55
5y = 15
Now, divide both sides by 5 to find the value of y (the number of $10 bills):
5y/5 = 15/5
y = 3
So, André has 3 $10 bills in his piggy bank. Now, we can use this value to find the number of $5 bills using the second equation:
x + 3 = 11
Subtract 3 from both sides:
x = 11 - 3
x = 8
So, André has 8 $5 bills in his piggy bank.
