Answer:
52%
Step-by-step explanation:
First, find the difference between this year's sales and the previous'. 1500-990=510.
Now we can divide 990 by 510 to find the percent increase. 510/990=0.515151515152, or 52%.
Answer:
x = -5/7
Step-by-step explanation:
8/(x+3)=1/(x+1)
Using cross products
8*(x+1) = 1*(x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x+3-x
7x +8 =3
Subtract 8 from each side
7x+8-8 = 3-8
7x = -5
Divide by 7
7x/7 = -5/7
x = -5/7
