Assuming she pleaded guilty, Ms Price received near enough the maximum sentence (albeit suspended, but see below) for the offences. The maximum is six months (182 days) but she is entitled to a one third discount for her guilty plea, so making the maximum 122 days. She was sentenced to 112 days.
//I'm not sure of what the usual sentence would be for that but it may have been suspended due to pleading guilty.//
Pleading guilty is not a consideration when deciding whether to suspend a prison sentence or not. A guilty plea reduces the signature sentence (i.e. the custodial term) by a third (if the plea is entered as early as possible). The question of suspending the sentence is an entirely separate consideration. It is not a simple matter but some guidance is given two thirds of the way down this page (if you’re asked to log in simply hit “Cancel” and the page should load):

Please don’t ask me to justify the District Judge’s decision. We don’t have all the facts and it would be impossible.
As an aside Ms Price would have served just 28 days of her 112 days had she been sentenced to immediate custody. She would have been eligible for release automatically at the half way stage (56 days) but would also be eligible to release under “Home Detention Curfew” after half of that half had been served (so at 28 days).
