Answer:
n = m − a
Step-by-step explanation:
Given:
a = m - n
Where,
a = Actual cost an item
m = Original price
n = amount of coupon
Solve the formula for the amount of the coupon
a = m - n
Add n to both sides
a + n = m - n + n
a + n = m
Subtract a from both sides
a + n - a = m - a
n = m - a
Amount of coupon, n = Original price of an item, m - Actual cost of an item, a

Answer:
There would be 6 boxes, each with 3 toys, 8 books and 9 crayons.
Step-by-step explanation:
Find the greatest common factor of 18, 48 and 54 (the toys, books and crayons).
18 = 2*3*3
48 = 2*2*2*2*3
54 = 2*3*3*3
All of them have at least one 2 and one 3.
The greatest common factor is 6 because 2*3 is 6.
There will be 6 boxes.
The number of each item is the total items divided by number of boxes.
18/6 = 3
48/6 = 8
54/6 = 9
There would be 3 toys, 8 books and 9 crayons in each box.
