Answer:
114
Step-by-step explanation:
19x6=114
4(m+3+5m) 4(m+3+5m)
4(6m+3) 4(6m+3)
4x6m+12 or 4x3(2m+1)
= 24m+12 = 12(2m + 1 )
Consider, pls, this option:
1) let start price is 'x' and the 1-t increasing is 'y';
2) after the 1-t increasing new1_price is x(y+1);
3) after the 2-d increasing new2_price is 1.25x(y+1);
4) from another side, new2_price is '2x';
5) according to five items it is possible to make up an equation: 1.25x(y+1)=2x;
1.25(y+1)=2, y=8/5 -1=3/5=0.6.
0.6 means 60%.
Answer: 60%.
