<u>Answer</u>: If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.
<u>Step-by-step explanation</u>:
Let x be the customer's total amount.
It is given that 15% of the customer's total = $22.05
⇒15% of x= $22.05
Therefore, If 15% of the customer's total is $22.05, then the customer's total is <u>$147</u>.
Answer:
Step-by-step explanation:
Given triangles are similar, so we setup a proportion
(140-x)/81 = x/9
solving gives x = 14
AC = 140-x = 140-14 = 126

Step-by-step explanation:</h3>
Let "a" and "c" represent the numbers of adult and children's tickets sold, respectively. The problem statement tells us two relationships between these values:
... 20a +10c = 15000 . . . . . . total revenue from ticket sales
... c = 3a . . . . . . . . . . . . . . . . relationship between numbers of tickets sold
Using the expression for c, we can substitute into the first equation to get ...
... 20a +10(3a) = 15000
... 50a = 15000
... a = 15000/50 = 300 . . . . . adult tickets sold
... c = 3·300 = 900 . . . . . children's tickets sold
