Answer:

150 for lower seats and 200 for higher seats

Step-by-step explanation:

Need two equations and then solve using substitution method:

Equation 1 for tickets sold:

$35x + $25y = $10,250

Equation 2 for quantity (number #) of tickets sold:

x + y = 350

Use substitution method:

y = 350 - x

35x + 25 (350 - x) = $10,250

35x + $8750 - 25x = $10,250

10x + $8750 = $10,250

        - $8,750       -$8,750

10x = 1,500

x = 150

 

y = 350 - 150

y = 200

Check the answers:

$35 (150) + $25 (200) =

$5,250 + $5,000 = $10,250

Answer:

45

Step-by-step explanation:

3 out of 12 is 1/4, or 0.25, so if you divide 180 by 4, then using the same logic, you can expect 45 kids to have played last year.

3 = 1/4 OR .25 of 12, 12 divided by 4 = 3

180 divided by 4 = 45
