6 minutes because 6 x 2 is 12.
Firstly, we’d have to find the total price paid for erasers by subtracting the overall price from the amount she paid in pencils.
$4.25 - $1.75 = $2.50
From there, we can use the amount per eraser to find out how many erasers she bought. Since she spent $2.50 in erasers, we can multiply to find our missing number.
$0.25 x 10 = $2.50
Therefore, Stefanie bought 10 erasers.
Hope this helps! :)

Answer:
f(0) = 3x
g(-2) = 3x + 6
Step-by-step explanation:
f(x) = 3x
3x = 0
x= 0/3
x = 0
g(x) = 3x+6
3x+6= 0
3x= -6
x= -6/3
x = -2
