Answer:
101
Step-by-step explanation:
To get the largest weighted sum, you want to give the largest weight to the largest possible digit.
Max( ) = 7·9 +3·8 +2·7 = 63 +24 +14 = 101 . . . . (x, y, z) = (7, 8, 9)
The maximum sum is 101.
1 day equals 24 hours.
18 hours / 24 hours = 0.75 days
The total days is 5.75 days.
Multiply the amount the bulb uses in 1 day by 5.75 days:
3600 x 5.75 = 20,700 watt-hours.
The area is 1. Hope this helps.:)
