Question

Problem The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance. The dance will cost $400. Write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance. What is the solution set of the inequality?

Answer 1

Answer:

Step-by-step explanation:

Per ticket earns by ticket  = $4;

Cost of bake sale = $72 [they have to pay]

so the solution of inequality is;

400 ≤ 4t + 72;

t is number of tickets;

Now calculating the t  = ?

400-72 ≤ 4t;

82 ≤ t ;

They have to sell more than 82 tickets for left over the money

Answer 2

Answer:

Inequality: 400-72<4t

Step-by-step explanation:

Solution set of the inequality: t > 82
