Respuesta :

340, percentage increased by 20% (percent) of its value = 408

Answer:

408

Step-by-step explanation:

you could do this 2 ways;

1.   20% of 100 is 20 so 100 + 20 = 120 so 20 * 3 = 60, 340 + 60 = 400

then 20% of 40 is 8 so 400 + 8 = 408

OR

2. do 340 * .20 = 68, 340 + 68 = 408

hope this helps you for future ones! :)
