SOMEONE HELP ME PLS In a certain country, income tax T (in dollars) is assessed according to the following function of income x:
T(x) =

0 if 0 ≤ x ≤ 10,000
0.05x if 10,000 < x ≤ 20,000
1000 + 0.18x if 20,000 < x
Find T(5,000), T(12,000), and T(25,000).
T(5,000) = $
T(12,000) = $
T(25,000) = $

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

b and c

step-by-step explanation:

4.5%

step-by-step explanation:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
