Answer
Ethan bought 4 packages of pencils. After he gave 8 pencils to his friends, he had 40 pencils left over. How many pencils were in each package? Use the drop-down men solve the problem arithmetically and algebraically.
Click the arrows to choose an answer from each menu.
To determine the solution arithmetically, first Choose...divide by 40 or add 8 to 40 or subtract 8 from 40
and then
Choose...subtract 8 from the result or divide the result by 4 or add 8 to the result
To determine the solution algebraically, set up and solve the equation Choose... 4x — 8 = 40
4х + 8 = 40 4 （2+8）=40 4 (x - 8) = 40
Each package contained Choose...12 or 8 or 18 or 2
- pencils.
Answer
Wampum beads, made from whelk shells and white and purple clam shells, and hairpipe beads, made from bone or shells, are commonly used in the jewelry of Eastern Woodlands tribes. The table shows the total number of these two types of beads sold by an online store over a 4-week period. If the sales trend continues, will the number of hairpipe beads sold always exceed the number of wampum beads sold?

Yes, because the total number of hairpipe beads sold increases exponentially and the total number of wampum beads sold increases linearly.

No, because the sales of each type of bead increase linearly and the difference between the number of the two types of beads sold decreases as the number of weeks increases.

No, because the wampum bead sales increase exponentially and the hairpipe bead sales increase linearly.


Yes, because the total number of each type of bead sold increases exponentially and the number of hairpipe beads sold in week 1 is greater.

To determine the solution arithmetically, first subtract 8 from 40 and then divide the result by 4.

To determine the solution algebraically, set up and solve the equation 4x - 8 = 40.

Each package contained 12 pencils.
