For this problem, your first want to create an equation by changing the words you're given into math.
You know that a = hours assigned by her teacher and c=hours Kiera practices. You also know Kiera practices 13 more hours than what her teacher assigns, a. That means:
c (hours Kiera practices) = a (how much she is assigned) + 13 (how much more she practices.
Your final equation is: c = a+13.
You're asked to find c when a = 1. Just put 1 in for a in your equation:
c = a+13
c = 1+13
c = 14 hours
