Round 810662.2 to 2 significant figure

810000

Step-by-step explanation:

Rounding to significant figures has the same concept in decimal places whereby a number is 5 or above it get's rounded up and when 4 or below it gets rounded down but the concept that makes rounding significant figures different to rounding decimal places is that you truncate it at the specified number

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
