Bonita worked 48 hours last week. Her hourly rate is $12.50. She is paid 1 1/2 times her regular rate for overtime hours. She has the following deductions taken from her gross earnings: ∙ federal income tax withheld at the rate of 10% ∙ Social Security tax withheld at the rate of 6.2% ∙ Medicare tax withheld at the rate of 1.45% ∙ health insurance premiums of $25.00 What is Bonita’s net pay?

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
