c=50+7p
The number of people is the indep. variable.

Ok, so we know that the pavilion cost $50, and that every person cost $7 to attend, so the cost (c) is equal to (=) $50 (the pavilion's cost) plus (+) $7 per person (p), it is stated as 7p because you multiply 7 x the number of people that attend.

so we multiply 7 to 50

noseboy908 · Answer

no, because 50 is not affected by a variable, it is a constant number, therefore, you add 50 to 7 x the number of people attending. The expression therefore is: cost for party=50(7 x the number of people attending)
