Multiple Choice
In a basketball tournament, Team A scored 5 fewer than twice as many points as Team B. Team C scored 80 more points than Team B. The combined score for all three teams was 983 points. Write an equation to represent this scenario using the variable b to represent Team B’s total points. Which equation represents this situation?
2(b - 5) + b + (b + 80) = 983
(2b - 5) + (b + 80) + 983 = b
(2b - 5) = (b + 80) + b
(2b - 5) + b + (b + 80) = 983

Multiple Choice
Two companies rent moving trucks. Pack and Go charges a $39.95 flat fee, and $0.45 for every mile driven. U-Drive charges a $59.95 flat fee, and $0.35 for every mile driven. At how many miles is the cost of the truck rentals the same?
What expression represents Pack and Go?
39.95x + 0.45
39.95 + 0.45x
39.95x + 0.45x

What expression represents U-Drive?
59.95 + 0.35x
59.95x + 0.35x
59.95x + 0.35

Which equation represents this scenario?
39.95 + 0.35x = 59.95 + 0.45x
0.45x + 0.35x = 39.95 + 59.95
39.95 + 0.45x = 59.95 + 0.35x
39.95 + 0.35x + 0.45x = 59.95
