Adult and student tickets were sold for the school play. The total receipts were $2005. The number
of student tickets sold was equal to three times the number of adult tickets sold decreased by 56. If
student tickets cost $3.50 and adult tickets cost $5.00, how many adult tickets were sold?

The number of adult tickets sold is 142

Step-by-step explanation:

Step 1:

Let the number of adult tickets sold be x. Then the number of student tickets sold = 3x - 56. Then, cost of adult tickets = 5x and the cost of student tickets = 3.50(3x - 56) = 10.5x - 196. Also, total receipts = $2005

Total cost = Cost of student tickets + Cost of adult tickets

⇒ 2005 = 10.5x - 196 + 5x

⇒ 2201 = 15.5x

⇒ x = 2201/15.5 = 142

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
