$15.60/130=0.12 [130 for 100 % + 30% increase]
0.12(100)=$12.00 [100 for 100 %]
Therefore, Alayna earns $12.00 per hour.

After a 30% increase, Alayna now earns $15.60 per hour. What was her hourly wage before the increase?

Since she received a 30% increase, then her hourly wage is now 130%, or 1.3 (100% + 30%)

Since 130% or 1.3 represents $15.60, then by using proportions, we can say that: 1.3%2F1+=+15.6%2FW, with W being her hourly wage before the inccrease

1.3W = 15.6 ----- Cross-multiplying

W, or hourly wage before increase = 15.6%2F1.3, or $highlight_green%2812%29
