Question One
The first question is just to derive a formula that represents the cost of anything bought in Idaho.
c = p + 6/100 * p
c = p + 0.6 * p
c = 1.06 p
Question Two
The second question requires an entirely different formula. You don't use the first formula. You just use it's idea. Further, you take the sales tax only when you know how much money has exchanged hands.
c = (p - 30/100 p) + 6/100*(p - 30/100 * p)
c = (p - 0.3p) + 0.06* (p - 0.3p)
c = 0.7 p + 0.06*(0.7p) Combine the right side
c = 0.7p + 0.042p Combine
c = 0.742p
33.39 = 0.742p Divide by 0.742
33.39/0,742 = p
p = 45 dollars
The original cost was 45 dollars
Answer:
-44
Step-by-step explanation:
first term is -4, second -9, third -14, fourth -19, etc.
there is constant difference (-5) between each two neighbor terms
you can use calculator by pushing the following buttons: -4-5========
the method is:
1) insert first term (-4)
2) insert a difference (-5)
3) push the "=" button 1 time less than the desired term number
So, if you must find 9th term, you push "=" button 8 times
after pushing buttons -4-5======== you get a result -44 on a calc
Answer:
Estimated profit margin this year = 95%
Step-by-step explanation:
Profit Margin = $50,000
Receivable this year = $1,168,000
Gross profit From the year = $1,168,000-50,000
=$1118000
Percentage profit margin this year = 
=0.95 * 100
=95 %
Estimated profit margin this year = 95%
