1 answer

Let the number of packages Sam bought be represented by x.

Since each package contains 9 beads, the total number of beads in the packages is 9x.

When Sam's mom bought him 63 more beads, the total number of beads he has is now 9x + 63.

Since Sam has 153 beads in total, we can set up the equation 9x + 63 = 153.

Subtracting 63 from both sides, we get 9x = 90.

Dividing both sides by 9, we find that x = 10.

Therefore, Sam bought 10 packages.
