Answer:
25
Step-by-step explanation:
Given the equation :
T = 200 - 4R
T = amount of money left ; if T = $100
R = number of rides
$100 = 200 - 4R
$100 - $200 = - 4R
-$100 = - 4R
R = 100/ 4
R = 25
25 rides
Cost of 1 set = 5t + 3j

Answer:
h = 7
Step-by-step explanation:
18 = (h - 1) × 6 × 0.5
simplify:
18 = 3(h - 1)
distribute the 3:
18 = 3h - 3
add 3 to both sides:
3h = 21
divide by 3:
h = 7
