Answer:
75 roasted turkeys.
Step-by-step explanation:
Ally's Eats had 75 roasted turkeys.
Bob's Goods had 4/5 as many roasted turkeys as Ally's Eats, hence, the number of roasted turkeys Bob's Goods had is:
4/5 * 75 = 60 roasted turkeys
Ally's Eats had 5/6 as many roasted turkeys as Charlotte's Market. In other words, Charlotte's market had 6/5 as many roasted turkeys as Ally's Eats:
6/5 * 75 = 90 roasted turkeys.
The average is given as the sum of all toasted turkeys in the three shops divided by 3. Hence:
A = (75 + 60 + 90) / 3
A = 225 / 3 = 75 roasted turkeys
The average number of roasted turkeys in the three shops is 75.
