Question

The cost of a school dance is given by the formula: c = 2p + 500 where c represents the total cost in dollars, and p the number of students attended. How many students can attend the school dance if we have $1,672 to spend on the dance?

Answer 1

586 students can attend the school dance if we have $1,672 to spend on the dance.

Explanation:

1672 = 2p + 500 Subtract 500 from both sides of the equation

1172 = 2p Divide both sides of the equation by 2

586 = p
