Step-by-step explanation
From the statement, we know that:
• the total revenue for this year is $33500,
,
• this revenue is 33% less than the total revenue of the previous year ,x,.
Using these data, we can write the following equation:
![\begin{gathered} \text{ revenue this year }=\text{ revenue last year - 33\% revenue last year}, \\ \text{\$33500}=x-0.33\cdot x, \\ \text{\$33500}=0.67\cdot x, \\ x=\frac{\text{\$33500}}{0.67}=\text{\$50000.} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/8yvgwnis2za69j1j4tgfsrqtxuc0zkzeus.png)
