Answer:
Jan wants to save a $2000 gift from her grandparents, and add $50 per month as emergency funds.
Bank A pays a fixed rate of interest, and Bank B pays a variable rate, but both rates are currently the same.
Based on her own needs, I would advice Jan to look out or few things like -
When you are expecting to save more money, you should prioritize about the interest rates as they will have an effect on your accounts and balance.
You should also look for the chargeable fee and services that are applied on that account as these make a big difference on the account when you have little balance. The type of interest (fixed or variable) does not matter that much. When you have more money in account then these fee looks negligible.
Answer:
37.5%
Step-by-step explanation:
The markup would be 37.5%. 80-50 = 30. If you set up the
proportion, is/of = %/100, it would be 30/80 = %/100. Multiply
30*100. = 3,000. Divide this by 80 and you get 37.5.
Answer:
x > 3
Step-by-step explanation:
6x + 3 > 21 (Move the constant, +3 to the right hand side and change its sign)
6x > 21 -3 (Subtract 21-3)
6x >18 (Divide both sides by 6)
x > 3
It would be greatly appreciated if you gave me the brainlest
This is what you call systems of equations. Basically were the two equations cross on a graph is the solution
You can solve this multiply ways... Graph, table, Substitution, elimination...
I will choose elimination because it is the easiest for how the equations are set up.
So
4x+2y = 200 2x+7y=400
First I take the second equation and multiply it by 2..
2(2x) + 2(7y)= 2(400)
4x+14y=800
Now I can just subtract the two equations
4x+2y = 200
-(4x+14y=800)
____________
-12y=-600
Solve for y
-12y/-12=-600/-12
y=50
Plug back in
4x+2y = 200
4x+2(50)=200
4x+100=200
-100 - 100
4x=100
4x/4=100/4
x=25
(25,50)
To check if you are correct you can use something like desmos (online graphing tool) and see if (25,50) is were the two lines cross.
You can also use substitution if you prefer.
