The total price before tax is $(38.75 +41.10) =79.85 and after tax the purchase price is 79.85 x 9.5% = $7.59 + $79.85= $87.44
Answer:
Sixty-three percent is the statistic and 39% is the parameter.
Step-by-step explanation:
Answer: 3
Explanation:
It is useful to summarise the information in the form of a table with columns for distance, speed and time.
Remember if you know two of these, you can write an expression or answer for the third one.
s = d/t and t = d/s and d = s × t
We have that the speed on Monday was x miles per hour and the time, 1/2 an hour. We can find the distance as x × 1/2
Show this on the table and then complete it for Tuesday as well.
Distance Speed Time
−−−−−−−−−−−−−−−−−−−−−−−−
Monday 1/2 x x 1/2
Tuesday 1/2 x (x-2) 3/4
The speed on Tuesday can be given in two ways:
It is the same as on Monday (1/2 x) or as s × t
Form an equation: 3/4 (x-2) = 1/2 x
4 x 3/4 (x-2) = 4 x 1/2 x ← x 4
3 (x-2) = 2x
3x - 6 = 2x
x = 6 ← this was the speed on Monday.
The distance run on Monday was 1/2 x 6 = 3 miles
