X will be used for the value of money she earned that week.
H represents the normal hours she worked.
D represents the number of days.
Y will represent the hours on the holiday.
Since she would be getting time and a half on the holiday, you would need to find how much time and a half pay would be first.
Time and a half = 5.50(1/2) + 5.50 = $8.25/hr for the day or holiday only.
X = 5.50(H)(D) + 8.25(Y)
Plug in your numbers
X = 5.50(7)(5) + 8.25(4)
X = 192.5 + 33
She made $225.5 that week.
Solve for x:
8 - 5 x = 2 x + 8
Subtract 2 x from both sides:
8 + (-5 x - 2 x) = (2 x - 2 x) + 8
-5 x - 2 x = -7 x:
-7 x + 8 = (2 x - 2 x) + 8
2 x - 2 x = 0:
8 - 7 x = 8
Subtract 8 from both sides:
(8 - 8) - 7 x = 8 - 8
8 - 8 = 0:
-7 x = 8 - 8
8 - 8 = 0:
-7 x = 0
Divide both sides of -7 x = 0 by -7:
(-7 x)/(-7) = 0/(-7)
(-7)/(-7) = 1:
x = 0/(-7)
0/(-7) = 0:
Answer: x = 0
Reduce all of the mutiple choices
A. 4/3 . It is greater than 3/4. 4/3 as a decimal is 1.333. 3/4= 0.75
B. 12/12. 12/12=1. 1 is greater than 3/4
C. 9/16. Cannot reduce the fraction.
D. 12/16 divide by 4 for the numerator and denominator. 12/4=3 , 16/4= 4
Answer: D. 12/16
The types of items that cost less than $3.75 per item are Paperbacks and notebooks.
<h3>How do we determine the price of a unit item in a word problem?</h3>
The price of a unit item can be determined by dividing the total price by the number of units sold.
Given that:
Paperbacks sold 3 units for $10.65;
- 1 unit will be sold for = $10.65/3 = $3.55
Notebooks sold 4 units for $14.36;
- 1 unit will be sold for = $14.36/4 = $3.59
Puzzles sold 3 units for $11.85;
- 1 unit will be sold for = $11.85/3 = $3.95
Picture frame sold 4 units for $15.20;
- 1 unit will be sold for = $15.20/4 = $3.80
Therefore, from the above calculations, we can conclude that the types of items that cost less than $3.75 per item are Paperbacks and notebooks.
