Hi, I am having hard time figuring this out. I don't really care about the answer, but I need to understand the "how to" really well, so as much detail in the solving would be ideal. Word problem: Tuition fees for California State University were $5,131 during the 2010-2011 academic year. Historically, tuition has increased at an 8% per year rate. Use the formula from Problem 83 to find what the tuition was 20 years ago and 30 years ago. Hint: First solve for P, then substitute the given value for F. Round to the nearest dollar. (equation in #83 to use here is F=P(1+r)² where F is the future price of an item priced at P dollars, r is the inflation rate expressed as a decimal, and t is the time in years)​

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o

Someone answer this asap rn for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
