Ms. Collier's family has a dinner bill of $26 and wants to leave a 15% tip for their server.
How much tip are they leaving?

Step-by-step explanation:

Meal $26.   tip = 15%

cost times 115%  = money left

26(1.15) = $29.90

$29.90-$26.00 = $3.90 in tips

$3.90

Step-by-step explanation: 26 times .15 = 3.9 which is $3.90

my answer is$ 12

step-by-step explanation:

because 15 -2=12

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
