The tip for a $78.00 restaurant bill is 9.20. What is the tip for a $21.50 meal?

$2.54

Step-by-step explanation:

Tips are percentages of the meal prices.  Divide the tip by the meal price to find the percentage that the tip is of the meal.

9.20/78.00 = 0.118 = 11.8%

Multiply the second meal by the percentage calculated.

21.5 × 0.118 = 2.54

The tip for the second meal is $2.54

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
