I'm having a really hard time understanding this question, can someone help me please I would really appreciate it A certain product costs $10 to make and the relationship between quantity sold q is dependent the price p

q = 1200 - 20p

The profit equation is Total Revenue (p*q) minus Production Cost (10q)

profit = pq - 10q

Using substitution, create a quadratic equation and find the price that maximizes profit.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

hope this !
