Diana and Russ ate a meal costing $77.40 when they went out to dinner. If they want to leave a 20% tip for the server, how much will they tip and what will their total be?

Respuesta :

Answer:

tip = $ 15.48

total = $ 92.88

Step-by-step explanation:

[tex]\frac{Amount (part)}{Base (whole)} =\frac{percent}{100}[/tex]

[tex]\frac{x}{77.40} =\frac{20}{100}[/tex]

[tex]77.40 * \frac{x}{77.40} =\frac{20}{100} X\frac{77.40}{1}[/tex]

[tex]x =\frac{1548}{100}[/tex]

x = $ 15.48 (20% tip)

then you add the tip tp the cost of the meal for the total

$ 77.40 + $15.48 = $ 92.88
