I believe 900 meters your welcomes
Profit = 8%
If the briefcase was marked down 20% from 1500 you multiply 1500 x .2 = 300 in order to calculate the discount.
Calculate the discounted price:
1500 - 300 = 1200
Calculate 10% discount of 1200:
1200 x .1 = 120
Calculate the sales price:
1200 - 120 = 1080
The last step is to calculate the profit/loss is the cost is 1000.
The briefcase sold for 1080 and the company paid 1000 for it, so there was a profit of 80.
The percentage is calculate by dividing 80/1000 = 8% profit
Answer:
4x-3
Explanation:
3x+2+x-5
4x-3
Hopefully the math terms won't confuse anyone.
So in the series, a_6 = 9 and a_8 = 15. Since it's an arithmetic sequence, all the terms in the series can be represented as:
a_n = a_0 + n * k
where n is the nth number. K is a constant you add to reach the next term, and a_0 is the starting constant.
a_6 = a_0 + 6 * k
a_8 = a_0 + 8 * k
solving this system gives you that
k = 3 and a_0 = -9
for any term n for this arithmetic sequence,
a_n = -9 + 3 * k
