On monday, nita earned $85 for h hours of babysitting. on wednesday, she earned the same rate for 8 hours of babysitting and got a $12 tip. write an expression to represent how much nita earned on wednesday.

You don’t know how long or how much she got paid an hour on Monday.  All you know is:

h = total number of hours she babysat on Monday, and she made $85.

Let r = the rate she got paid per hour on Monday, then rh = 85, and then r = 85/h

On Wednesday she babysat 8 hours at the same rate of 85/h and got an additional $12

The expression for how much she made on Wednesday is:   8(85/h) + 12

step-by-step explanation:

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
