The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $5.50 and each adult ticket sells for $8.50. The auditorium can hold at most 110 people. The drama club must make no less than $680 from ticket sales to cover the show's costs. Also, they can sell no more than 70 adult tickets. If xx represents the number of student tickets sold and yy represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
Answers
Answer:
74 or 73
Step-by-step explanation:
We are going to assume that the show is sold out. If 66 student tickets were sold, we only have 74 adult tickets to sell. Based on that information, we then have to use an inequality to find out if the number of adult tickets we have to sell to meet our money requirements is more than the amount of seating we have left after 66 seats were taken by students. Our inequality looks like this:
5.50(66) + 7.50(a) ≥ 910 and
363 + 7.50a ≥ 910 and
7.50a ≥ 547 so
a ≥ 73
In order to meet our money requirement, we have to sell 73 adult tickets. Since we have 74 seats left, we are good.

Find the first five terms of the sequence defined below, where n represents the position of a term in the sequence. Start with n=1. 10n+10
Answers
Answer:
20,30,40,50,60
Step-by-step explanation:
The sequence is given by the relation as follows :
[tex]a_n=10n+10[/tex]
First term, n = 1
[tex]a_1=10(1)+10=20[/tex]
Second term, n = 2
[tex]a_2=10(2)+10=30[/tex]
Third term, n =3
[tex]a_3=10(3)+10=40[/tex]
Fourth term, n = 4
[tex]a_4=10(4)+10=50[/tex]
Fifth term, n = 5
[tex]a_5=10(5)+10=60[/tex]
So, the first five terms of the sequence are 20,30,40,50,60
Last year , Henry opened an investment account with 5800. At the end of the year ,the amount in the account had increased by 29.5 how much is this increase in dollars?How much money was in his account at the end of las year?
Answers
Answer:
Percent increase in dollar = $1,711Total in account = $7,511Step-by-step explanation:
The money in the account had increased by 29.5%.
This increase in dollars is:
= Amount in account * percentage increase
= 5,800 * 29.5%
= 5,800 * 0.295
= $1,711
The total in his account was therefore:
= Amount invested + increase
= 5,800 + 1,711
= $7,511
