From the bar graph, we have:
Sales in first quarter (Jan - Mar) = $155,000
Sales in second quarter(Apr to JUn) = $232,500
Sales in third quarter (Jul to Sep) = $135,000
Sales in fourth quarter (Oct to Dec) = $160,000
Let's find the percent increase in sales from the first to second quarter.
To find the percent increase from first to second quarter, apply the formula:
![\text{Perecent increase = }\frac{Sales\text{ in Q2 - Sales in Q1}}{Sales\text{ in Q1}}*100](https://img.qammunity.org/2023/formulas/mathematics/college/dln8atlvtd4e9rwq737jov0ydikcnpme52.png)
Thus, we have:
![\begin{gathered} \text{Percent increase=}(232500-155000)/(155000)*100 \\ \\ \text{Percent increase = }(77500)/(155000)*100 \\ \\ \text{Percent increase = 0.5 x 100 = 50\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/rgn9bem3nv617kthnmnyhqkd1czqsuehn2.png)
Therefore, the percent increase from first to second quarter is 50 percent.
ANSWER:
50%
