Clearing Decimals in Retail Budgeting

As an assistant manager at a local retail store, you are reviewing a budget calculation sheet. A colleague is trying to solve the simplified equation 0.30x+0.15=2.85{}0.30x + 0.15 = 2.85 to find the number of standard promotional displays, xx, to order. They are unsure of the standard procedure for clearing decimals. State the mathematical reason why 100 is chosen as the multiplier to clear the decimals in this equation, and explain how the number of decimal places present in the equation determines this choice.
