First we have to calculate how many dozen eggs he sold
for this we will multiply the number of total dozens by the 5/6 that sold
12 * 5/6 = 10
She sold 10 dozen eggs
each dozen eggs comes out $4.50 so we multiply the number of dozens of eggs that sold (10) by the price of each ($4.50) and we will get the money that was obtained from the sale
