Answer:
$28
Step-by-step explanation:
SO,
5.5% OF SOME NUMBER is 1.54 dollars. Right?? Yes!
SOME NUMBER is what we are looking for, that is the ORIGINAL PRICE OF THE BOARD GAME.
We can let original price [some number] be "x" and write the word equation as algebraic equation shown below:
Note: 5.5% = 5.5/100 = 0.055
Now, we just simpyl solve for x:
$28 is the original price
The package with the most low cost is 7.
Answer:
either x or y must equal 0
Step-by-step explanation:
ts given that xy = 0
Remember that product of two numbers can be zero only if:
Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.
So, if the product of x and y is equal to 0 there are two possibilities:
Both x and y are equal to 0
Either x or y must be equal to 0
Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.
Hence, the condition which has to be true in all cases for xy = 0 is:
either x or y must equal 0
Answer:
The first account earns an interest of $511.11
Step-by-step explanation:
a). Interest in the first account
The total amount of interest earned in 10 years can be expressed as;
Compound interest=(P(1+r/n)^nt)-P
Where;
P=Principal amount
r=Interest rate
n=number of times the interest is compounded annually
t=number of years the account is kept
In our case;
P=$900
r=4.6/100=0.046
n=1
t=10 years
Replacing;
Compound interest=900(1+0.046/1)^(1×10)-(900)
Compound interest=900(1.046)^10-(900)
Compound interest=1,411.105-900
Compound interest=$511.105
Nearest cent=1/100=0.01 two decimal places
511.105=511.11
The first account earns an interest of $511.11
