Answer: 5.79
Step-by-step explanation:
From the question,
3 people ordered the 4.75 chicken dinner. The cost will be:
= 4.75 × 3
= 14.25
2 people ordered the 4.95 fish dinner. The cost will be:
= 4.95 × 2
= 9.9
5 had beef dinner at cost of 6.75 each. This cost will be:
= 6.75 × 5
= 33.75
Total cost will be:
= 14.25 + 9.9 + 33.75
= 57.9
Therefore, the average cost of each dinner at Mary's party will be:
= Total cost / Number or people
= 57.9 / 10
= 5.79
