Answer:
$478.80
Step-by-step explanation:
We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.
First of all, we will find cost of each meal with tax as:
[tex]\text{Cost of each meal with tax}=\$12+\$12\times \frac{5}{100}[/tex]
[tex]\text{Cost of each meal with tax}=\$12+\$12\times 0.05[/tex]
[tex]\text{Cost of each meal with tax}=\$12+\$0.6[/tex]
[tex]\text{Cost of each meal with tax}=\$12.6[/tex]
Now, we will find total persons at the sport banquet as:
[tex]\text{Total persons at banquet}=15+2+21[/tex]
[tex]\text{Total persons at banquet}=38[/tex]
To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.
[tex]\text{Total cost of food for the banquet}=\$12.6\times 38[/tex]
[tex]\text{Total cost of food for the banquet}=\$478.8[/tex]
Therefore, the total cost of food for the banquet is $478.80.
