Question

The members of the art club are making keychains that require 18 beads apiece. The art club adviser brought a bag with 250 beads for them to use. If there are 70 beads left in the end, how many keychains were made?

Answer 1

The number of keychains made can be found by subtracting the number of beads used in the keychains from the total number of beads the art club adviser brought. To find the number of beads used, you can subtract the number of beads left from the total number of beads the art club adviser brought.

So the number of keychains made is:

Number of keychains made = Total number of beads - Number of beads left

= 250 - 70

= 180

To find the number of keychains made, you can divide the number of beads used by the number of beads per keychain,

So the number of keychains made is:

Number of keychains made = Number of beads used / Number of beads per keychain

= 180 / 18

= 10 keychains

10 keychains were made.
