You spend $11 on school supplies. you purchase pencils for $.25 each and pens for two dollars each. you purchase a total of 30 pencils and pens how many of each did you purchase

If each pencil is $0.25 each, and you purchase 30 pencils, then the equation is:
0.25 x 30 = $7.5

$11 - $7.5 = $3.5
This means you have 3.5 dollars to spend on pens. 
If each pen is $2, you only have enough money to buy one pen.

Remaining money: $1.5
Total money spent: $9.5

Hope this helps! Good luck.
