Aubrey's dinner cost $85. she tips the waitstaff 30 percent for excellent service. how much does aubrey tip the waitstaff

$25.50 thats how much she tip the waitstaff.

Total cost for Aubrey's dinner = $85

The percent she tips the waitstaff = 30%

we have to determine the amount which Aubrey tip the waitstaff.

The amount she tips the waitstaff = of Dinner cost

= 30% of $85

=

=

= $25.5

Therefore, Aubrey tips $25.5 to the waitstaff.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
