Mr. Velazquez can buy #40# pencils

We can write the following equation:

#0.12p=4.80#

Where #p# is the number of pencils which cost #$0.12# per pencil and #4.80# is the amount of money that Mr. Velazquez has to spend.

So we solve the equation for #p#

#0.12p=4.8#

Divide #0.12# from both sides:

#cancel0.12/cancelcolor(red)0.12p=4.80/color(red)0.12#

#p=40#

So he can buy #40# pencils exactly
