How can we solve multistep equations that represent real-world scenarios?

• Determine the variable.

• Identify key words and translate the meaning.

• Write the multistep equation.

• Solve for the variable.

• Use the value of the variable to solve the problem.

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.

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. What expression represent the points for Team A?

• b

• b + 80

• 2(b - 5)

• 2b - 5

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

In a basketball tournament, Team A scored 5 less 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. Let the variable b represent Team B’s total points. The equation representing this scenario is (2b – 5) + b + (b + 80) = 983. Team B scored 227 total points. How many points did Team C score?

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
