Answer:
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.
