Given problem,
8 + (-4)
Since, in the number line the numbers left to zero are negative and right to zero are positive,
When, we move towards a negative number then we move left side while when we move towards a positive number then we move right side,
Thus, the steps involve in the given problem are follow,
Step 1 : Find 8 on the number line,

Answer: After 3 hours both will have the same cost.
Step-by-step explanation:
Let x = Number of hours and y be the total cost.
Total cost = Initial cost + (cost per hour)(Number of hours)
At Mike's Bounce Shop,
Total cost (y)= 30+2x
At Jose's Bounce Rentals,
Total cost(y) = 12+8x
When both shops have the same cost, then
Total cost = 12+8(3)=12+24=$36
Hence, After 3 hours both will have the same cost.
