Gavin has $20 to spend at an arcade. He spends $8.75 on lunch and plans to use the rest of his money on game tickets. Each game ticket costs $1.25. The inequality 1.25t+8.75 ≤20 can be used to find t, the number of game tickets Gavin can buy. What is the solution to this inequality?

9 tickets

Step-by-step explanation: you have to subtract the $8.75 from lunch and then divide it by $1.25 to see the maximum quantity of tickets he can purchase with his remaining money

16 / 81

Step-by-step explanation:

Between digits 0 ,1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9

Prob (prime number) = Prime numbers / Total numbers ; Prime numbers = 1,3,5,7. So, Prob = 4 / 9

Prob (composite number) = Composite numbers / Total numbers ; Composite numbers = 2, 4, 6 , 8.  So, Prob = 4 / 9

Prob (Prime & Composite) = 4 / 9 x 4 / 9 = 16 / 81
