Final answer:
Bruno cannot have any quarters and dollar bills.
Step-by-step explanation:
Let's represent the number of quarters Bruno has as x. Since Bruno has seven more dollar bills than quarters, we can represent the number of dollar bills as x + 7.
The value of quarters is 0.25x and the value of dollar bills is 1(x + 7). Since the total money is $3.25, we can write the equation:
0.25x + 1(x + 7) = 3.25
To solve this equation, we simplify:
0.25x + x + 7 = 3.25
Combining like terms, we get:
1.25x + 7 = 3.25
Subtracting 7 from both sides of the equation, we get:
1.25x = -3.75
Dividing both sides of the equation by 1.25, we get:
x = -3
Since it doesn't make sense to have a negative number of quarters, there is no solution to the problem. Therefore, Bruno cannot have any quarters and dollar bills.
