Q. There are xx packages of pencils. Each package of pencils cost $2.50\$2.50 before tax, totaling $81.00\$81.00, which included 8%8\% sales tax. Find xx.
  1. Calculate Pre-Tax Total: Now we got the pre-tax total which is $75\$75. Next, we need to find out how many packages of pencils that is. Each package costs $2.50\$2.50, so we divide $75\$75 by $2.50\$2.50 to get the number of packages. 752.50=30\frac{75}{2.50} = 30
  2. Determine Number of Packages: So, we bought 3030 packages of pencils.
