Suppose a room service waitress at the Sun and Sand Resort receives gratuity represented by the equation g = 0.15b, where g represents the gratuity and b represents the food bill. What percent gratuity does the room service waitress
receive? How do you know?

If the food bill is $19, how much tip did she receive?

If the room service waitress receives a $2.10 gratuity, how
much is the food bill?

it alot will look like this 4.4

step-by-step explanation:

i used the pitagoras theoreme

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
