Answer: 5
Step-by-step explanation:
F(x) = ax + b
maka..
f(1) = 3
a(1) + b = 3 --> a+b = 3
f(2) = 5
a(2) + b = 5 --> 2a+b = 5
untuk mencari nilai a dan b nya, di eliminasi, maka dapat
a=2 dan b=1
Answer:
$68 and $10.792
Step-by-step explanation:
The computation is shown below:
The total bill received by them is $56.80
The total bill after adding 19% tip is

=$56.80 + $10.792
= $67.592
= $68
The sever would make the amount i.e. equivalent to the tip amount i.e $10.792
