Tickets at the theater or $9 for adults seniors receive a discount and only have to pay $6 but capicity of the theater is 80 people. If the theater was at full capacity and made $675, then how many seniors bought tickets for the movies? And how did you get that answer

Answers

Answer 1

Answer: so $9 for adults and $6 for seniors

so number of adults is represented by x
number of seinors is represented by y

9x+6y=675 since every adult pays 9 and seinors pay 6

x+y=80 since adults+seinors=80

multiply x+y=80 by -6
-6x-6y=-480
add this to 9x+6y=675
9x-6x+6y-6y=675-480
3x+0=195
divide both sides by 3
x=65
there were 65 adults

subsitute 65 for x in x+y=80
65+y=80
subtract 65 from both sides
y=15

there were 15 seinors at the event

Jeremy is opening a savings account earning simple interest. He plans to deposit his $50 birthday money and leave the account alone until he goes to college. He will earn $5 per year in interest.

Answers

Answer:

10%

Step-by-step explanation:

Use the formula of simple interest:

$A=P(1+rt)$

We can determine the interest rate if he earns $5 a year. Which means after a year he will have $55. Let A be the final amount after year t with t=1:

$55=50(1+r(1))$

Solve for r, the interest rate:

$5=50r$

$r=5/50=0.1$

Jeremy will earn money in the firsts year at a interest rate of 10%
