Ace ate lunch at a family restaurant. after he finished, he paid the waitperson $17.25. that amount included the cost of the food and also the tip. the tip was 15% of the price of the food. how much money did ace give to the waitperson for a tip?

Ace give to the waitperson amount of $ 2.25 as a tip

Step-by-step explanation:

Given as :

The total amount paid to waitperson = $ 17.25

I.e Amount of food + amount for tip   = $ 17.25

Let the amount of food  = $ x

So, The amount of tip = 15% of $ x

∴  $ x + 15% of $ x      = $ 17.25

Or, × $x = $ 17.25

Or, 1.15 × $x   = $ 17.25

∴               x    = = $ 15

So,       The Amount of food = x =$ 15

And      The Amount of waitperson = 15% × x = 15% × 15 = $ 2.25

Hence, Ace give to the waitperson amount of $ 2.25 as a tip   Answer

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

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)
