Answer:
10.50x ≤ 205
The maximum number of tickets, x, would be 19.
Step-by-step explanation:
Given,
The cost of one ticket = $ 10.50,
The cost of x tickets = 10.50x dollars,
Since, the total cost can not exceed $ 205,
⇒ 10.50x ≤ 205
∵ 10.50 > 0 thus, when we multiply both sides by 1/10.50 the inequality sign will not change,
⇒ x ≤ ≈ 19.52
Hence, the maximum number of tickets would be 19.
Answer:
X=-8
Step-by-step explanation:
A number x is multiplied by 4, added to 3, and then divided by x+2, leaving us with 7/2. Or, as an equation:
Now, let's cross multiply:
And solve:
