Linda works at a pharmacy for $15 an hour. She also babysits for $10 an hour. Linda needs to earn at least $90 per week, but she does not want to work more than

Question

I am really lost on this question. I thought I knew what it was, but when I looked in the book I was incorrect. If possible, I need all the work shown.

Answer 1

Let x equal the number of hours at the pharmacy and y equal the number of hours babysitting. Then

15x +10y = 90

Now the last part of your question did not show up above but I am assuming that the total hours where specified, let call that T. So the second equation is:

x + y = T

Then these equations can be solved by substitution or any other preferred method of solving simultaneous equations.

Answer 2

I would think she could work 4hrs @ pharmacy and 3hrs @ babysitter would be the answer.
