Total balance in Mr. Copley at the end of the month = $1473.61.
Initial deposite = $75 (not shown in his checkbook).
Let us assume his balance at the beginning of the month = x.
Total balance at the end of the month = The balance at the beginning of the month + total deposite.
$1473.61 = x + 75.
Subtracting 75 from both sides, we get
1473.61 -75 = x + 75 -75.
1398.61 = x.
Therefore, his balance at the beginning of the month was $1398.61.
Answer:
2 $
Step-by-step explanation:
let the original price be x
price after 10% discount = 3.60$
The original price of 2 pens is 4$
original price of one pen = 4/ 2
<u>= 2 $</u>
Step-by-step explanation:
$31.50 is how much she made
418.5 is how much the store made, but, that is the simple value, there could be more variables
Answer:
To avoid expansion, you can just use the power of a power rule and multiply the two exponents from the start.
Step-by-step explanation:
(<em>x</em>^4)^3
= <em>x</em>^4×3
= <em>x</em>^12
Answer:
0.75c
Step-by-step explanation:
If we have an expression as:
a*x + b*x
We can see that both terms in the expression, a*x and b*x have an x, so we can call the x a common factor and we can write an equivalent expression as:
a*x + b*x = (a + b)*x
If we replace, for example, a by 2, b by 3 and x by 4, we can test the expression as:
2*4 + 3*4 = (2 + 3)*4
8 + 12 = (5)*4
20 = 20
Therefore, if we have the following expression:
c - 0.25*c
The expression that is equivalent is 0.75c and it is calculated as:
c - 0.25*c = (1 - 0.25)*c
c - 0.25*c = 0.75*c
