Final answer:
To calculate the increase in earnings for Cho, we take 1/3 of her current earnings of $298 to find she will earn approximately an additional $99.33. In total, she will make about $397.33 next month.
Step-by-step explanation:
The question is asking how much more Cho will make next month if she earns 1/3 more than her current earnings of $298. To calculate this, we take 1/3 of $298 and then add it to the original amount.
1/3 of $298 is calculated as 298 / 3 which gives us approximately $99.33. So, Cho is estimated to make an additional $99.33 next month on top of her current earnings.
Therefore, next month, Cho will make about $397.33, which is her current earnings of $298 plus the additional $99.33.
