Without additional information about the intended analysis, it is impossible to calculate a p-value. However, based on the fact that the table is labeled "Chi-Square Test" and given the size of the table, it is likely that a test of independence (i.e., testing whether age group and income level are related) was conducted using a chi-square test. If this is the case, and if any cells have expected frequencies below 5, then the chi-square test may not be appropriate and the p-value may not be reliable. Assuming none of the expected frequencies are below 5, a p-value larger than 0.05 would suggest that age group and income level are not significantly related, while a p-value smaller than 0.05 but larger than 0.01 would suggest a significant relationship at a relatively strict level of significance.
