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
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.
