Answer:
Option 1
Step-by-step explanation:
To find which will cost more, we need to know the amount of interest that will be on each loan
To get this, we use the general formula
I = PRT/100
Where P is the principal I.e $2,000 in both cases, R is the interest rate and T is the time.
We proceed as follows. For the first option
I = (2000 * 7 * 3)/100 = $420
For the second option
I = (2,000 * 1 * 12)/100 = $240
Option 1 is definitely more costly
Answer:
x=-1, y=2
Step-by-step explanation:
Plug the y=-2x into the second equation in place of the y to get 4x+10(-2x)=16
Simplify this to 4x-20x=16 then to -16x=16
Divide both side by -16 to get x=-1
Plug x=-1 into the first equation to get -2(-1)=y
Simplify to get y=2
