Maria bought 15 pencils each pencil cost .22 how much did it cost her to buy 15 pencils

2

Step-by-step explanation:

Of the $24, she has $10 left, therefore, she spent $14 on the 7 pencils.  

You can tell now how much each pencil cost, since 7 goes into 14, 2 times.

The answer is the cost for each pencil= $2.

However, in order to represent the problem using equations:

Assign a variable for the cost of each pencil, let x represent the cost

$24 equals 7 pencils, each x dollars worth, and the $10 left over: 24=7x+10.

Solve for x,  

                24-10=7x

14=7x

$2=x

The cost of each pencil is $2.
