Katherine was out at a restaurant for dinner when the bill came. Her dinner came to $34. She wanted to leave a 13% tip. How much was her meal plus the tip, before tax, in dollars and cents?

(x), therefore when we equate the two equations the result should be similar to

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
