Sam Seller pays a local club $40 a month. Each week he has dinner for a flat fee of $20.00. Sam takes a cab, which charges him $1.75 for the first half-mile and $1.00 for each mile after that. The club is 5.5 miles from Sam's home, and he tips the driver $5.00 when he gets home. What does this meal cost Sam? (Don't forget the club membership for that week.)

Respuesta :

Answer:

The correct answer is $ 48.5

Step-by-step explanation:

  • Club membership cost for one week

[tex]=\frac{40}{4}\\=10[/tex]

  • Cost of dinner = $ 20
  • Cab charges =

[tex]= ( 1.75 + 5 )\cdot 2 + 5\\=18.5[/tex]

{ the fare is doubled because he will return to home also but the tip is paid only once so it is not doubled }

Total Cost = 10 + 20 + 18.5 = $ 48.5
