Answer:

The average cost of each dinner at Dave's party is $5.79.

Step-by-step explanation:

Given:

Dave ordered dinner for a party of 10 people.

Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.

Now, to find the average cost of each dinner at Dave's party.

So, we get the total amount for the dinner:

Three people ordered the $4.75 chicken dinner.

[tex]4.75\times 3=14.25[/tex]

Two people ordered the $4.95 fish dinner.

[tex]4.95\times 2=9.90[/tex]

Five had the beef dinner at a cost of $6.75.

[tex]6.75\times 5=33.75[/tex]

Total amount of dinner = [tex]14.25+9.90+33.75=\$57.90.[/tex]

Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:

[tex]57.90\div 10[/tex]

[tex]=\$5.79.[/tex]

Therefore, the average cost of each dinner at Dave's party is $5.79.
