Yolanda makes $11.25 per hour at her part-time job. During one week, she worked 1225 hours and also earned some tips. Her final pay for the week was $159.50. How much money did Yolanda earn in tips?

she earned $20 in tips

Step-by-step explanation:

- figure out how much she'll get payed in 12 hours of work, :

12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

now you need to subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20, so basically thats how i got 20.
