Knowing that multiplication and addition are the two operations needed to solve the problem, write the equation and solve.

The swim team and the diving team sell popcorn to raise money for their team swimsuits. They sold 12 bags of regular popcorn for $6 each and sold 10 bags of caramel corn for $8 each. How much money did they earn?

• (12+6+8) X 10=M

  M=$260

• (8+6) X (12+10)=M

  M=$80

• (12X6) + (10X8) = M

  M=$152
