Joey has a collection of action figures. He separates them into small, medium, and large figures. He has 4 times as many small figures as medium figures. The number of large figures is 6 less than 2 times the number of medium figures. He has a total of 43 action figures. Using the equation x + 4x + 2x - 6 = 43, solve for x.

• x = 6.16 medium figures

• x = 5.28 medium figures

• x = 7 medium figures

• x = 8.16 medium figures

Student Council is collecting coins for the food pantry. They collected 8 times as many dimes as quarters, 30 less nickels than dimes, and 4 times as many pennies as nickels. They collected a total of 389 coins. What is the correct equation for all of the coins?

• 8x + 8x - 30 = 389

• x + 8x + 8x - 30 = 389

• 8x + 8x - 30 + 4(8x - 30) = 389

• x + 8x + 8x - 30 + 4(8x - 30) = 389
