10. A travel agency advertises the following deal on a cruise. If 100 people register for the trip, the cost will be $1,000 per person. For every additional ten people who register, the price of the cruise will drop $25 for each person. Express the revenue R as a function of the number of $25 and x.

R(x) = 1000 - 25	R(x) = 975x	R(x) = (100 -10x)(1000 + 25x)
R(x) = (100 + x)(1000 - x)	R(x) = (100 +10x)(1000 - 25x)
