Answer:
12 more people adopted a manatee this year.
Step-by-step explanation:
Convert 30% into a decimal. Divide the percentage by 100:
30 / 100 = 0.3
The problem can be solved with the following equation:
0.3(40) = difference
Multiply 0.3 by 40.
0.3 * 40 = 12

Answer:
The system is given by the two equations:
x + y = 100000
0.06*x + 0.085*y = 0.08*(100000)
Step-by-step explanation:
The total money Connor has is $100,000. He wants to split it between two accounts, therefore the money that he'll apply on one account "x" plus the money that he'll apply on the other account "y" must be equal to the total he has. The first equation of the system, must be:
x + y = 100000
Since the first account gives a return of 6% and the second account gives a return of 8.5%, then the first account will give a return of 0.06*x and the second account will give a return of 0.085*y. The sum of this values must be equal to what he desires to recieve, therefore:
0.06*x + 0.085*y = 0.08*(100000)
The system is given by the two equations:
x + y = 100000
0.06*x + 0.085*y = 0.08*(100000)
1/3y=x
3•1/3y=3x
y=3x
Hope this helped, if it did, I would really appreciate it if you can give me brainliest
