John and 3 friends are going out for pizza for lunch. they split one pizza and 4 large drinks. the pizza cost $13.00. after using a $6.00 gift certificate, they spend a total of $13.20. write an equation to model this situation, and find the cost of one large drink. 4d + $13.00 – $6.00 = $13.20; $1.55 4d – $13.00 + $6.00 = $13.20; $6.73 3d + $13.00 – $6.00 = $13.20; $2.07 4d + $13.00 – $6.00 = $13.20; $1.60

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)) =

Which number completes the system of linear inequalities represented by the graph? y> 2x – 2 and x + 4y 2 et 2 3 4

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41
