Find the equation using the point (4,8)

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96

Solve for x: 5/3 x = 20/21 it's fraction. remember to simplify your fraction
