Answer:

Step-by-step explanation:
Expand the binomial and collect terms.
If Deshawn’s goal was to raise three-fifths of $1000 you need to fond out what a fifth of 1000 is. You divide 1000 by 5 to get 200. Since it is three fifths you multiply that by 3 which equals $600. Now if Deshawn only reached five-sixths of $600 you need to find out what a sixth of 600 is so divide 600 by 6 which equals 100. Now you multiply that by five as it is 5 sixths of the goal which equals $500. So the answer would be - Deshawn raised $500.
Answer:
n = m - a
Step-by-step explanation:
Given:
a = m − n
Where,
Actual cost of the item = a
Original price of the item = m
Amount of Coupon = n
Solve the formula for the amount of the coupon
Making n the subject
a = m − n
Subtract m from both sides
a - m = m - n - m
a - m = - n
Divide both sides by -1
(a - m) / -1 = -n / -1
- a + m = n
Can also be written as
n = m - a
