How would you write a real-world problem that models the following equation 0.08x=0.06x+140

A company purchases two types of raw materials, materials A and B, to produce their final product. The cost of materials A is $0.08 per unit, while the cost of materials B is $0.06 per unit. The company wants to determine the number of units of materials A they need to sell in order to cover the cost of materials B, plus an additional $140 in expenses.

The equation representing this real-world problem is:
0.08x = 0.06x + 140

Where:
x represents the number of units of materials A the company needs to sell.
