Answer:
The school baseball team sold 270 tickets
Explanation:
Step 1
Identify the total amount of tickets sold by each player;
1 player=1 book of tickets
But 1 book=10 tickets
Step 2
Express the total cost of ticket sales per book as follows;
total cost=cost per ticket×number of tickets per book
where;
cost per ticket=$3
number of tickets per book=10
replacing;
total cost=(3×10)=$30
Step 3
Using the expression below, solve for the number of tickets sold
Total amount raised=price per ticket×number of tickets sold
where;
total amount raised=$810
price per ticket=$3
number of tickets sold=n
replacing;
810=3×n
3 n=810
n=810/3=270
n=270
