Answer:
711.11
Step-by-step explanation:
<h3>Method 1 </h3>
If 777  is decreased by 12%. the number would now be (100% - 12%) 88% of what it was originally 
0.88 x 777 = 683.76
 683.76 is increased by 4%.  683.76 would now be (100 + 4%) 104% of what it originally was 
 683.76 x 1.04 = 711.11
<h3>Method 2 </h3>
12% x 777 = 
0.12 x 777 = 93.24
777 - 93.24 = 683.76
4% x 683.76 = 27.3504
683.76 + 27.3504 = 711.11
