Answer:
$4,500
Step-by-step explanation:
For simple interest,
I = prt,
where
I = interest
p = principal
r = annual interest rate
t = number of years
We have p = $5,000, r = 9% = 0.09; t = 1 year
I = $5,000 × 0.09 × 1
I = $450
Answer:
24 and 36
Step-by-step explanation:
2x + 3x = 60
5x = 60
x = 12
Dawn has 2(12) = 24
Jackson has 3(12) = 36
Answer: $86.25
Step-by-step explanation:
For this problem, we are given p, r, t.
p=70 (starting amount)
r=0.11 (11%)
t=2 (years)
We can plug this into the equation B=p(1+r)^t
B=70(1+0.11)^2
B=86.247
Sam would have $86.25
To fill the squares look for the one filled in column/row/diagonal and figure out its sum.
All other columns/rows/diagonals must be equal to that, so whenever there is a column/row/diagonal with a single missing value you can add the others up and calculate the missing value.
So you have to find those single missing value columns/rows/diagonals, fill them out and continue with the next one until the whole square is filled in.
Just use the formula y=mx+b and you should get your answer
