Question Sam is buying packages with 9 beads each. His mom bought him 63 more beads. Now, he has 153 beads. How many packages did he buy? Use algebra to determine the answer

Answer 1

Let's call the number of packages that Sam bought as "x".
Since each package has 9 beads, the total number of beads Sam bought is 9x.
After his mom bought him 63 more beads, the total number of beads Sam has is (9x + 63).
We are told that Sam now has 153 beads, so we can write the equation:
9x + 63 = 153
Subtracting 63 from both sides of the equation:
9x = 153 - 63
9x = 90
Dividing both sides of the equation by 9:
x = 10
Therefore, Sam bought 10 packages of beads.
