Rate of change is 4. change of y over change of x= 20/5
Answer:
$15,589
Step-by-step explanation:
Since it deteriorated 15%, it is now worth 85% of the original.
18340 * .85 = 15589
3:5 is the ratio of cups of rice to cups of water.
Let us assume the amount of money invested in CD = x
Then
Amount of money invested in savings bond = 6000 - x
Percentage of interest in CD = 4%
Percentage of interest in savings bond = 7%
Amount of interest gained in 1 year = $360
Now
0.04x + [(6000 - x) * 0.07] = 360
0.04x + 420 - 0.07x = 360
0.03x = 60
x = 2000
Then
Amount of money invested in the CD account = $2000
Amount of money invested in savings bond = 6000 - 2000
= 4000 dollars
