Amount of tip she gave,
Amount of tax given :
So, total amount she paid is :
Total = Actual cost + Tip + Tax
Total = $(15 + 3 + 1.35 )
Total = $19.35 .
Therefore, total amount she paid is $19.35 .
Hence, this is the required solution.
<span>f(0)=3 and f(n+1) = -f(n) + 5 for n≥0
so f(1) = -f(0) + 5 = -3 + 5 = 2
f(2) = -f(1) + 5 = -2 + 5 = 3

16 = -5 + z/4
21 = z/4
21*4 = z
z = 84
P=3r + 2s you need to get all the numbers and variables on the other side of the equation so that s is alone.
P -3r = 2s Subtract the 3r from both sides.
P- 3r /2 =s now divide the whole amount P-3r by 2 and you've got your answer!
