Ten friends decide to get an end-of-year gift for their teacher. They plan to split the cost of the gift equally. But four of the group drop out. The remaining friends split the cost equally among themselves. If each share is now $8 more, how much does the gift cost, in dollars?

Define a variable ** Let N be the original price each friend was going to pay.
Write an equation ** 10N=6(N+8)
Simplify ** 10N=6N+48
Subtract 4N ** 4N=48
Divide by 4 ** N=<<12=12>>12
How much does the present cost? ** Then the present costs 10*12=<<10*12=120>>120.
