You can use calculus ( related rates). Given the rate os change of the radius for example you can find the rate of change of volume using differential calculus.
Let's examine this, as x increases by 1, what happens to the y-value? The y-value decreases by 2, so the slope is -2. When x = 0, we have our y-intercept, -5. So we can fill in Slope form with the Slope and Y-intercept that the equation is:
y = -2x - 5
Take ln to both sides
ln 14^x = ln 5
then you'll get
x ln 14 = ln 5
divide both sides by ln 14
x = 0.6098533345
after rounding
x = 0.6099

Answer:
$4.20
Step-by-step explanation:
you first do 1.75 divided by 5 which gives you .35
so you do .35 times 12 which gives you 4.2
