Sam is buying packages with nine beeds each. His mom bought him 63 more beads, he has 153 how many packages did he buy use algebra to determine the answer?
Let's represent the number of packages Sam bought with a variable, such as "P". We know that each package has 9 beads. Therefore, the total number of beads from the packages is 9P.
His mom bought him 63 more beads, so the total number of beads he has is 9P + 63.
We also know that Sam has a total of 153 beads, so we can set up the equation:
9P + 63 = 153
Now, let's solve for P by subtracting 63 from both sides of the equation:
9P = 153 - 63
9P = 90
Finally, to determine the value of P (the number of packages), we divide both sides of the equation by 9:
P = 90 / 9
P = 10
Therefore, Sam bought 10 packages.
