Answer-

The inequality equation for the given problem is "9.50(70+x) ≥ 1000"

And the theater need to sell 36 more tickets in order to get at least $1000.

Solution-

Let's assume x is the number of more tickets to sell in order to get at least $1000 and the price of one ticket is $9.50.

No. of tickets already sold by the theater = 70

So total earnings till now = $(70 × 9.50)

Total earnings by selling x tickets = $(x × 9.50)

∴ Hence, the inequality equation is,

[tex]70\times9.50 \ + \ x \times 9.50 \geq 1000[/tex]

[tex]\Rightarrow 9.50(70+x)\geq 1000[/tex]

[tex]\Rightarrow 70+x\geq105.26[/tex]

[tex]\Rightarrow x=35.26 \approx 36[/tex] ( ∵ since tickets can only be sold as whole)

∴ So, the theater need to sell 36 more tickets in order to get at least $1000.
