The firm's Total revenue will increase

Based on the information given we were told that the total revenue is currently an amount of $256.58 which means that If the producer decided to purchase three more units of b3, what would happen to the firm's total revenue is that the firm's TOTAL REVENUE will tend to increase reason been that the firm is selling more and in a situation where the numbers of units sold increase this means that the TOTAL REVENUE will as well increase.
Hence the increases in the price of the product for every single unit sold will lead to increases in TOTAL REVENUE.
