The equation a = p + prt is used to find the accumulated amount, a, of an investment with principal, p, a certain interest rate, r, and over time, t. what is the value for t, after the equation is rearranged?

t equals start fraction cap a minus p over p r end fraction
t equals start fraction cap a plus p over p r end fraction
t equals start fraction cap a minus one over r end fraction
t = a − p − pr

Need solving this second acceleration problem.

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)) =
