Answer 10

Each pizza costs $10
One pizza costs $10 * 1
Two pizzas cost $10 * 2
Three pizzas cost $10 * 3
etc.
x pizzas cost $10 * x, or 10x

She wants to spend less than $610, but she has already spent $500.
$610 - $500 = $110
She wants to spend less than $110 on pizzas.
That means the cost of the pizzas, 10x, has to be less than $110
10x < 110
Solve the inequality by dividing both sides by 10.
You get
x < 11
That means she can only buy less than 11 pizzas.
