Answer: Sales tax is $4.80 and the total cost is $64.80
Step-by-step explanation: Take the difference in the total before and after tax and divide by the price before tax.
To get $4.80, find the sales tax of $60.00 of 8%
We can use this formula: (selling price x sales tax rate)
The sales tax is: $4.80
To find the total cost, add 60.00 by the sales tax. ($4.80)
60.00 + 4.80 = $64.80
Therefore, these are your answers: $4.80 and $64.80
1) We have 1300 packing peanuts, and 20 ft^2. Therefore, to find out how many packing peanuts there are per square foot, we divide the number of peanuts (1300) by the number of square feet (20 ft^2). This gives us 1300 / 20 = 65 packing peanuts per square foot.
2) We do not know the current volume of the box which fits the 1300 packing peanuts (all we know is its area). But it is reasonable to expect that if we increase the volume by 25%, the number of packing peanuts will also increase by 25%. This means we can fit 1300*(1.25) = 1625 peanuts in the larger box.
3) This will depend on how the box is larger. If its height remains the same, and its floor area increases to accommodate the greater volume, then the number of packing peanuts per square foot remains the same.
However, if the height of the box is different, then the number of packing peanuts per square foot will change, since the floor area will not increase by the same 25% any more.

Answer:</u></h3>
The circumference of a circle with diameter of 98 in. is about 308 in.
<h3><u>
Step-by-step explanation:</u></h3>
<u>We know the diameter. Using the diameter, we can find the circumference.</u>
- => Diameter = 98 in.
- => Radius = 98/2
- => Radius = 49 in.
<u>Circumference = 2πr</u>
- => 2 x 22/7 x 49
- => 2 x 22 x 7
- => 308 in.
<h3><u>Conclusion:</u></h3>
Therefore, the circumference of a circle with diameter of 98 in. is about 308 in.

Answer:
Rate=9.05%
Step-by-step explanation:
Let P represent the Principal ,t the time = 8 years and r be the rate of interest.
It is given money doubles in 8 years so A=2P.
The compound interest is given by the formula :
Substituting the values we have:
Dividing both sides by P :
1.0905-1=r
r=0.09050
r=9.05%
Number of exams per semester = 5
Average of first four exams = 90
Therefore,
Total of first four exams = 90*4 = 360 marks
Based on 5 exams,
Average = 360/5 = 72
