If 15 people sign up, the price per person is $50. The registration fee is reduced by $2 for each additional camper beyond 15. The relationship between the number of registrations and revenue is given by y 5 (50 2x)(15 + x), where x represents the number of campers beyond 15 and y is the total revenue, in dollars. :1) Graph the quadratic inequality. ifsl. ll - us.._. o.- -v no. gun-1 - .gs. .L. -._L9__1._ . ._ ,3: . mist1F! we.rs b) What is the total number of registrations that will generate revenue of at least $500
