Question 402558
Write a proportion for the story problem & solve .
Denise Davis earns $475 for working a 40-hour week. At the same pay,
how much does she earn for working 18 hours?
:
Let x = amt earned in 18 hrs
{{{x/475}}} = {{{18/40}}}
Cross multiply
40x = 475 * 18
40x = 8550
x = {{{8550/40}}}
x = $213.75

We can confirm our solution by finding the hourly rate and multiplying by 18
{{{475/40}}} = 11.875
18 * 18.875 = 213.75
