Answer:
$3000
$1000
Step-by-step explanation:
the formula for simple interest = principal x time x interest rate
let the amount invested in the 2% investment be a
let the amount invested in the 3% investment be (4000 - a)
(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90
0.02a + 120 - 0.03a = 90
Collect like terms and solve for a
0.01a = 30
a = $3000
The amount invested in the 3% investment be (4000 - a) = $4000 - $3000 = $1000
Answer:
30/54
Step-by-step explanation:
1st make and equation so 5/9=x/54
now cross-multiply.
5/9=x/54
(5)*(54)=x*(9)
270=9x
you can flip the equation.
9x=270 (next divide both sides by 9)
x=30
so 30/54=5/9
hope this helps :)
In this item, it is assumed that we are to calculate for the depreciation rate of the sausage system. This can be calculated through the equation,
D = (P - S) / n
where D is the depreciation rate,
P is the present value of the sausage system, $500,000
S is the salvage value, $74,000
and n is the number of years, 5 years
Substituting the known values from the given in this item,
D = ($500,000 - $74,000) / 5
D = $85,200
The depreciation rate of the new sausage system that Frank will buy is $85,200/year
