Answer:
$3.88
Step-by-step explanation:
You want to leave a 18% tip on a meal that cost $21.58.
First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.
Second, you need to find out what 18% of your $21.58 meal cost is.This is always done by multiplying 0.18 by $21.58, or 0.18 x $21.58=$3.88.
So, the amount of tip you are going to leave is $3.88.

The equation of line is:

Further explanation:
The standard form of equation in point-slope form is:

Given equation is:
3x+2y=10
We have to convert it into point slope form, for which we have to isolate y on one side of equation

Comparing with standard form:
m = -3/2
As the new line is parallel to given line, their slopes will be equal
So,

To find the value of b, putting the given point (4,-5) in equation
