Answer:

50.6%

Explanation:

Start with a balanced chemical reaction, always. You need the molar ratios to determine percent yield.

#C_7H_6O_3 + C_4H_6O_3 -> C_9H_8O_4 + C_2H_4O_2#

In this case you could remember that they are 1:1, but I'm going to suggest you always find the balanced reaction, because in many cases the molar ratio will not be 1:1.

Remember to find the molar ratios and that the formula for percent yield is the actual/theoretical yield multiplied by 100.
