Answer:
4
Step-by-step explanation:
-2 + 6 = 4
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.
Answer: Total cost is $1.75
Explanation:
Since we have given that
Number of postcards bought by Doug's family= 7
Cost of each postcard including tax = $0.25
Total cost is given by

Now, we want to show this in number line :
On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.
Each step is of length 0.25 and there are 7 jumps to reach required answer.
So, after 7 jumps we reach at 1.75 which is the required answer.
Hence total cost is $1.75
Answer:
