There are 5 pencil-cases on the desk. Each pencil-case
contains at least 10 pencils, but not more than 14 pencils.
Which of the following could be the total number of pencils in
all 5 cases?

Answer 1

Answer:

Choose the numbers in the choices that are 50, 70, or any integer in between 50 and 70.

Step-by-step explanation:

Minimum number of pencils: 5 × 10 = 50

Maximum number of pencils: 5 × 14 = 70

The number of pencils ranges from 50 to 70. All integers 50, 70 and in between 50 and 70 are possible.

Choose the numbers in the choices that are 50, 70, or any integer in between 50 and 70.
