Question 551240


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: {{{1.3/1 = 15.6/W}}}, with W being her hourly wage before the inccrease


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


W, or hourly wage before increase = {{{15.6/1.3}}}, or ${{{highlight_green(12)}}}
