Answer:
The 2 boxes of nails will cost him $ 2.88.
Explanation:
Cost of a given substance is the amount of money needed to acquire it. The total cost involved in the purchase of a given number of units is equal to the cost of one unit multiplied by the total number of units.
Total cost = Cost of 1 unit × Total number of units ....equation 1
Given: Boxes of nails to be bought = 8
Price of 2 boxes of nails = ?
Assuming the money to be in dollars ($).
The given equation used to calculate the cost of 8 units or boxes of nails:
11.52 = (1.44)8 ....equation 2
By comparing equations (1) and (2), we get
The cost of 1 box of nails = $ 1.44
and the total cost of 8 boxes of nails = $ 11.52
∴ The total cost of 2 boxes of nails = cost of 1 box of nails × 2 = $ 1.44 × 2 = $ 2.88
Therefore, the 2 boxes of nails will cost him $ 2.88.
