Marcus wants to predict how much his gym membership will cost each month. He pays $19.99 each month for his membership and $45 for each personal training session.
Let x represent the number of times he has a personal training session each month
and y represent the total cost for his gym membership.
Write an equation Marcus can use to predict how much he will pay each month.

What is the expression in factored form? 3x^2 + 18x + 24 a. 3(x+2)(x+4) b. 3(x-2)(x+4) c. 3(x-2)(x-4) d. 3(x+2)(x-4)

Your food costs are $5,500. your total food sales are $11,000. what percent of your food sales do the food costs represent?

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
