The the s t r i t o n family had a meal catered for a wedding rehearsal dinner the cost of the dinner was $476 they're real 5% sales tax and they were left a 15% tip what was the total cost including the sales tax and the tip

Add 5% to the 15% you get 20%. now multiply 476 by 1.20 to get the total cost

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
