Question

Visitors to a carnival can buy an unlimited-ride pass for $50 or an entrance-only pass for $20. In one day, 282 passes were sold for a total of $10,680. How many unlimited-ride passes were sold? (2 points)

Answer 1

Have you been provided with any further information?

Answer 2

YES GENERALLY YOU R GIVEN MORE INFORMATION

Answer 3

$50 unlimited-ride passes are going to be variable a
$20 entrance-only passes are going to be variable b

282 passes were sold, so a + b = 282
$10,680 worth of passes were sold, so 50a + 20b = 10680

Answer 4

this is a system of equations problem. our equations being

a + b = 282
50a + 20b = 10680

Answer 5

use the first equation and solve for b

Answer 6

Solve @AriPotta

Answer 7

once you do that, you can substitute that for b in the second equation and solve for a

Answer 8

a + b = 282
b = 282 - a

50a + 20b = 10680
50a + 20(282 - a) = 10680

solve for a and you'll have your answer

Answer 9

you decided to use subsitution method

Answer 10

yes, that seemed like the best way to go, in my opinion

Answer 11

I would have gone for multiplying by -20

Answer 12

well, it doesn't really matter. either way, you'll get your answer :P

Answer 13

lets go then

Answer 14

i want @tqosborne to get the answer for him/her self

Answer 15

-20 a -20b = -20(282)
50a + 20b = 10, 680

Answer 16

ok

Answer 17

its up to you @tqosborne
