Answer: 14 pencils

Step-by-step explanation:

Each pencil costs $1.50, so you have to see how many pencils you can buy with $22. To begin, multiply 1.50 until it gets close to the money limit, which is $22.

$1.50*2 pencils= 3 dollars spent

$1.50*3 pencils= 4.50 spent

$1.50*4 pencils= 6 dollars spent

$1.50*5 pencils= 7.50 spent.

$1.50*6 pencils= 9 dollars spent

$1.50*7 pencils= 10.50 spent

$1.50*8 pencils= 12 dollars spent

$1.50*9 pencils= 13.50 dollars spent

$1.50*10 pencils= 15 dollars spent

$1.50*11 pencils= 16.50 dollars spent

$1.50*12 pencils= 18 dollars spent

$1.50*13 pencils= 19.50 spent

$1.50*14 pencils= 21 dollars spent

This is where you have to stop even though you haven't spent all of the 22 dollars yet because if you buy one more pencil, then the total will cost $22.50, which is over the budget.

Answer:

  14

Step-by-step explanation:

If Alicia buys p pencils, her cost will be ...

  1.5p . . . . . cost in dollars of p pencils

She wants that cost to be no more than $22, so ...

  1.5p ≤ 22

Dividing both sides of the inequality by 1.5, we get ...

  p ≤ 22/1.5

  p ≤ 14.66666... (repeating decimal)

The largest whole number of pencils Alicia can buy with $22 is 14 pencils.
