Answer 1

The expression to represent the total price of the supplies is 1.29n + 0.79w + 2.39b

Solution:

Let "n" be the number of nails

Let "w" be the number of washers

Let "b" be the number of bolts

Given that ,

Price of nail = $ 1.29 per lb

Price of washers = $ 0.79 per lb

Price of bolts = $ 2.39 per lb

To find: Expression to represent the total price of the supplies.

Total price = number of nails x Price of nail per lb + number of washers x Price of washers per lb + number of bolts x Price of bolts per lb

`Total\ price = n * 1.29 + w * 0.79 + b * 2.39\\\\Total\ price = 1.29n + 0.79w + 2.39b`

Thus the expression to represent the total price of the supplies is found
