Therefore, the missing value is -9.
We need to find the unit price of each box.
So, a box that weighs 30 Oz costs $4.50.
lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.
Unitary method is a process to find the value of a single unit.
Now,
30 Oz costs $4.50
therefore, 1 Oz should cost:
dollars
So, the unit price of box 1 is $0.15.
Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.
Now,
20 Oz box costs $3.60
therefore, 1 Oz should cost:
dollars
So, the unit price of box 2 is $0.18.
assuming
Then the column values for base five here are
5³ 5²
We can get 1 × 5³ = 125 → 219 - 125 = 94
We can get 3 × 5² = 75 → 94 - 75 = 19
We can get 3 x → 19 - 15 = 4
and 4 = 4 ×
Thus =
As a check
(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219
