20 customers are eating dinner at a local restaurant. The restaurant accepts cash or credit as forms of payment. Of the 20 customers, 4 have enough cash to pay for their meal, 16 have a credit card, and 3 have enough cash and a credit card. Using this information, answer each of the following questions. Let A be the event that a randomly selected customer has enough cash and B be the event that a randomly selected customer has a credit card.

A: 20% chance

B: 80% chance

Step-by-step explanation:

4 out of 20 people have cash: which means from a randomly selected group, you have a 20% chance of finding someone with enough cash

16 out of 20 people have credit card: which means from a randomly selected group, you have a 20% chance of finding someone with a credit card

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
