✔ 最佳答案
a) T = 3060 + (0.34)(x-20700)because the tax (T) = $3060 plus $0.34(34cents) for 'every $1 over $20700', which is x-20700
solve the right side of the equation:
T = 3060 + 0.34x - (0.34)(20700)
T = 0.34x + 3060 - 7038
T = 0.34x -3978
b) Sub x=32000 into the equation above to find the tax T
T = (0.34)(32000) - 3978
= $6902

a.Write a rule for the tax payable, $T, for a taxable income, $x, where 20701 <(大過或等於) x<(大過或等於) 38000
T=3060+(x-20700)x0.034
b. Calulate the tax paid on an income of $32 000.
T=(32000-20700)x0.034+3060
T=3060+(x-20700)x0.034
b. Calulate the tax paid on an income of $32 000.
T=(32000-20700)x0.034+3060
