Adalia ate lunch and wanted to leave her waitress a 15% tip. Her meal cost $8.95. How much money will the entire meal, including the tip, cost?

Total cost = $10.2925

Approximately $10.30

Step-by-step explanation:

Cost of meal = $8.95

Tip = 15% of $8.95

= 0.15 × 8.95

= $1.3425

How much money will the entire meal, including the tip, cost?

Total cost of the meal = Cost of meal + amount of tip

= $8.95 + $1.3425

= 10.2925

Total cost = $10.2925

Approximately $10.30

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
