Answer:
$2000
Step-by-step explanation:
let x be the money she invested
lets assume this was for 1 year
0.09(x/2) + 0.07(x/2) = 160
multiply each side by 2 to cancel the denominators:
0.09x + 0.07x = 320
0.16x = 320
x = 2000
Answer:10151 will be your answer
Step-by-step explanation:
The answer to the problem is 1,000
So it's 2.40 subtract 2, which is 0.4
then put it over 2, you get 0.4/2, which is equal to 0.2
0.2= 20% so it's 20% of increase
