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

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

good luck!
