richard and davina ate dinner at a restaurant together. davina had a coupon for 25% off their meal. they both agree that they should leave a 20% tip on their meal. however, richard believes they should calculate the tip before taking into account the coupon, and davina believes they should calculate the tip after taking into account the coupon. if their meal costs $48.80 before using the coupon, by how much will the tip increase if they use richard's method instead of davina's method?

Otto used 6 cups of whole wheat flour and cause x cups of white flour in the recipe. what is the equation that can be used to find the value of y, the total amount of flour that otto used in his recipe and what are the constraints on the value of x and y? a y=6x; x is any interger greater than the equal to 0 and y is an interger greater than the equal to 6? b y=6x; is any real number greater than or equal to 0 and y is any real number greater than or equal to 6? c y=+6; x is any intger greater than or equal to 0 and y is an intger greater than or equal to 6? d y=x+6; x is any real number greater than 0 eqaul to 0 and y is any real number greater than or eqaul to 6?
