- Mrs. Tobin's taxable income is $8,900. On this, she must pay 2% on the first $3,000, 3% on the next $3,000, and 4% on the balance
for state income tax. During the year, her employer had withheld
$4.50 per week. To settle her tax bill at the end of the year,
Mrs. Tobin had to pay an additional
(1) $32
(4) $226
(2) $31
(5) $225
(3) $59

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

the real question is why is this guys last name heavyfoot
