Answer:
32 one-dollar bills.
Step-by-step explanation:
Let <em>x </em>represent one-dollar bills and <em>y </em>represent two-dollar bills.
He has a total of 49 bills. Therefore:
The total amount of money James has is 66. <em>x</em> is worth one dollar, while <em>y</em> is worth two dollars. Therefore:
We have a system of equations. Solve by substitution:
Therefore, James has 32 one-dollar bills and 17 two-dollar bills.
Checking:
The solution of the system of equation is (-7, -2).
<h2>Given</h2>The system of the equations;
From equation 1
Substitute the value of y in equation 1
The value of x= 2 is rejected because x = 2 not satisfy the equation.
Substitute 2 for the value of x in equation II
y − x = 5
y – 2 = 5
y = 5 +2
y = 7 (x =2, y =7) … Not included in the options
If x = -7
Substitute the value of x = -7 in the equation
Hence, the solution of the system of equation is (-7, -2).
