An airplane can seat up to 175 passengers. the airline has already sold 87 tickets for a flight on the airplane. which graph represents the solution to the inequality that finds the number of tickets the airline can still sell?

answer

as given

an airplane can seat up to 175 passengers.

the airline has already sold 87 tickets for a flight on the airplane.

find out the   the number of tickets the airline can still sell.

to proof

let us assume that the airline can still sell be t.

as given

an airplane can seat up to 175 passengers.

the airline has already sold tickets = 87 tickets

than the inequality becomes

t + 87 ≤   175

t ≤ 175 -87

t ≤ 88.

the number of ticket still sell be 88 .

as the number of ticket   can still sell be lie between

0 ≤ t ≤ 88

this is shown in the grah given below.
