Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Just compare the change in unit cost to the original unit cost.
Shovels: (70.38 ÷ 2 - (172.50/5) ÷ (172.50/5) = 0.02
Salt: (26.04 ÷ 4 - (6.20) <span>÷ </span>6.20 = 0.05
So, the shovels went up 2% and the salt went up 5%
If I’m not wrong, it should be 1000-5+9.10% and add it to the tune and divide with the 9.90% and -3 and then you can get your answer
Answer:
26
Step-by-step explanation:
Let the peter's number be represented x
Given that
1. if you subtract 19 from my number
writing it mathematically it will be x -19
2. multiply the difference by -3
it can be written as
since difference is x-19
multiplied the difference with -3
-3(x-19)
3. the result is -21
-3(x-19) = -21
dividing both side by -3
-3(x-19)/-3 = -21/-3
x-19 = 7
adding 19 both sides
x-19 + 19 = 7 + 19
x = 26
Thus, peter's number is 26.
What temperature Is 6 degrees less than 2 degrees Celsius?All you have to do for this one is do 2-6 which is -4.
Hope I helped and good luck!
