1 answer

To solve this problem, we will complete the inequality in Part A and then calculate the minimum number of shirts in Part B.

Part A: Completing the Inequality

The band needs at least $1,150 to cover expenses, and they have already saved $700. This means they need to earn at least:

\[ 1,150 - 700 = 450 \text{ dollars} \]

They earn a profit of $7 per shirt, so the amount they earn from selling \( n \) shirts is \( 7n \).

The inequality representing the minimum number of shirts, \( n \), that they must sell to earn at least $450 is:

\[ 7n \geq 450 \]

Now, we place the correct tiles in the blanks:

7 [n] [] 700 [+] 1,150

Part B: Calculating the Minimum Number of Shirts

To find the minimum number of shirts, we will solve the inequality:

\[ 7n \geq 450 \]

Dividing both sides by 7:

\[ n \geq \frac{450}{7} \]

Calculating that:

\[ n \geq 64.2857 \]

Since the band cannot sell a fraction of a shirt, we round up to the next whole number:

\[ n \geq 65 \]

Thus, the minimum number of shirts the band must sell is 65.

Final Answers:

  • Part A: 7 [n] [] 700 [+] 1,150
  • Part B: 65 shirts
