Given data:
The total numbers of books are n=9.
The
Answer:
<h2>$326.25</h2>
Step-by-step explanation:
The question is incomplete as we were not given to numbers of adults and children, neveherless we can assume some figures and plug it into the expression
say number of adult is 15
and number of chidren is 30
In this problem we are going to the values of adults and children tickets into the expression for the total cost and return the answer, which is the total cost of tickets sold
given the expression
8.75 x+ 6.50y
substituting for x and y we have
8.75(15)+ 6.50(30)=
131.25+195=$326.25
The total cost for 15 adults and 30 children is $326.25
Answer:
His gain percent would have been 8%
Step-by-step explanation:
The key to answering this question is to first calculate the price at which the wheat flour was bought.
Mathematically;
% profit = (selling price-cost price)/cost price * 100%
Let the cost price be $x
Thus;
% profit = (30-x)/x * 100
20 = 100(30-x)/x
20x = 3000-100x
100x + 20x = 3000
120x = 3000
x = 3000/120
x = Rs 25
So let’s assume he sold at Rs 27
His profit would have been 27-25 = 2
His gain or loss percentage would’ve been;
2/25 * 100/1 = 200/25 = 8% (gain, since selling price is greater than the cost price)
