y-intercept for x = 0.
Substitute x = 0 to the equation of the function:
We can solve this problem by rule of 3:
$30 (taxes)------------$100
x-----------------------$3,680
x=($30*$3,680) / $100=$1,104
Answer: $1,104 paid in taxes.
To divide fractions, you multiply by the reciprocal.

Answer:
It will be quadrupled
Step-by-step explanation:
we know that
All spheres are similar
so
The ratio of the surface areas of two spheres is equal to the scale factor squared
Let
z ----> the scale factor
x ----> surface area of the sphere with radius doubled
y ----> surface area of the original sphere
so
The scale factor is 2 (because the radius of the sphere will be doubled)
substitute
so
The new surface area is 4 times the original surface area
therefore
The surface area will be quadrupled
