Question

A bounce house can hold 15 children. Seven children go in the bounce house. Write and solve an inequality that represents the additional number of children that can go inside.

A) 7 + x < 15
B) 7 + x > 15
C) 7 - x > 15
D) 7 - x < 15

Answer 1

The additional number of children that can go inside the bounce house is represented by the inequality 7 + x < 15, where x represents the number of additional children. By subtracting 7 from both sides, we find that x < 8.

Step-by-step explanation:

To write the inequality that represents the additional number of children that can go inside the bounce house, we can use the following expression:

7 + x < 15

This inequality states that the sum of the initial number of children (7) and the additional number of children (x) must be less than the maximum capacity of the bounce house (15). To solve this inequality, we can subtract 7 from both sides:

x < 15 - 7

Simplifying the inequality gives:

x < 8

Therefore, the answer is A) 7 + x < 15.
