How do I show this on paper. I know the answer is $56.00. Only because I eat out alot, and can figure the tip easy, but to show this on paper yikes...
Selena left a 15% tip for a meal. The tip was $8.40. What was the cost of the meal before the tip?

sorry I am looking at your graft, and i can only read tip: percentage 8.4 : 15 then something? : 100. Am I cross multiplying 8.4 x15 to multiply to 100? Im not sure what your demonstrating sorry...

let 'x' be the cost of meal. 15% tip for a meal = 8.4 so, 15% of x = 8.4 (15/100 ) x = 8.4 can you find 'x' from here ?

something = x. Actually we use the ratio method here. he first ratio we were given was $8.5 corresponds to 15%. dw:1359350664298:dw We have to find the 100% value of the tip (which will be the cost of the meal) dw:1359350678428:dw And then we cross multiply.

x % means x/100 15 % means 15/100 15% of x = (15/100)x = 15x/100 = 8.4 now can you find 'x' ? first multiply both sides by 100 to eliminate the denominator, what u get ?
