Answer:
2.24
Step-by-step explanation:
This problem can actually be changed from a subtraction problem to an addition problem. Two negative signs together make a positive.
So, the problem becomes:
-96.43
+ 98.67
Now, remember this phrase to help solve problems like this:
Same sides add and keep. Different signs subtract. Keep the sign of the higher number.
In order to solve this equation you must eliminate one of the variables.
By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37

Answer:
Step-by-step explanation:
3a. Jackson's gross pay for 40 hours is
(40 h)×($12.20/h) = $488.00
3b. An equation for Jackson's pay could be
372.10 = h×12.20
This can be solved for h by dividing by 12.20
372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.
3c. The total of hours shown is
(8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.

Of course, you know the decimal - fraction conversions:
1/4 = 0.25
1/2 = 0.50
3/4 = 0.75
T + 0.03t......simplified = 1.03t....with t being the original price
original price is 72....
so the total cost (including tax) is :
1.03t...when t = 72
1.03(72) = 74.16 <==
