Question

Dimitri is helping to plan the school talent show. Each performer for the talent show has 7 minutes for his or her performance, which includes transition time between performances. If the introduction for the talent show is 25 minutes long and the entire show, including the introduction, will last 130 minutes, how many different performances can the talent show accommodate?

Answer 1

15 performances can be accommodated

Solution:

Given that,

Each performer for the talent show has 7 minutes for his or her performance

The introduction for the talent show is 25 minutes long

The entire show including the introduction, will last 130 minutes

Thus the remaining time for performances is:

Performance time = 130 minutes - 25 minutes

Performance time = 105 minutes

To find, the number of performances, divide the 105 by 7 minutes

$Number\ of\ performances = \frac{105}{7} = 15$

Thus 15 performances can be accommodated
