A company is selling bubble gum.  The function g(x)=3x+4 tells the company how much to charge if someone buys x packages of bubble gum.  Find g(8) and tell what it means within the context of the problem.

• g(8)=8. This means that after 8 packages of gum, the company makes $8.

• g(8)=42. This means that 8 packages of gum costs $42.

• g(8)=28. This means that 8 packages of gum costs $28.

• g(8)=24. This means that 8 packages of gum costs $24.
