Adita earns $9.40 per hour working at an animal shelter. How much money will she earn for 18.5 hours of work?

1 Answer

Answer:

#x=$173.9#

Explanation:

Thinking about proportion can help here. First, let call X how much she earns.
So, Adita earns #$9.40 = 1hr#
then, #x=18.5hrs# Since these are proportional and equal to hours we could set them into a fraction that money earns equal to hours worked.
Hence;
#($9.40)/x=(1hr)/(18.5hrs)# to remove the denominators, we will multiply both sides of the equation by the denominators(cross multiply)
#x*(($9.40)/x)*18.5hrs=18.5hrs((1hr)/(18.5hrs))*x#
#$173.9hrs=x(hr)# find x, x is how much she earns.
#x=$173.9#
