4. Mr Vidal puts (c) gallons of gasoline in my car at a price of $1.98 per gallon. His wife, Taylor Swift, puts (z) gallons of gasoline in her car at a
price of $2.28 per gallon. Together they spend $58.43 putting gas in their
cars. Write a linear equation in terms of x and y that represents the
scenario.

1.98c + 2.28z = 58.43

Step-by-step explanation:

.

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
