Answer:
50 dgrees
Step-by-step explanation:
staruight line is 180 so 180 minus 130 is 50
For 356 ticket, each ticket is $80, so all of those tickets cost 356 × 80 = $28,480.
For 275 ticket, each ticket is $60, so all of those tickets cost 275 × 60 = $16,500.
For 369 ticket, each ticket is $45, so all of those tickets cost 369 × 45 = $16,605.
For all of the tickets the box office took in you have to do:
28,480 + 16,500 + 16,605 = 61,585
<u>The answer is $61,585.</u>
