Answer:
This is not a solvable question, since the least amount of money you can have with this combination is $4.20.
Step-by-step explanation:
Let q = quarters
Let d = dimes
Equation: 0.1d + 0.25q = 3.00
Maximum amount of dimes: 0.1d *42 = 4.2d
3x+4y=12
9x-2y=15
we will use elimination
multiply 3x+4y=12 by -3
-9x-12y=-36
9x-2y=15
_________ add
-14y=-21
÷-14 both sides
y=1.5
find x
3x+4 (1.5)=12
3x+6=12
-6 both sides
3x=6
÷3 both sides
x=2
x=2
y=1.5
