I'll do a similar problem, and I challenge you to do this using similar techniques!
If John works for 15$ a hour with his friends rather than working for 20$ an hour for 50 hours a month, what's the monthly opportunity cost?
John would make 20*50=1000 dollars a month at the second option as he makes 20$ an hour 50 times. Next, if he works with his friends, he makes 15*50=750 dollars as he works 50 hours for 15 dollars an hour, or adds 15 50 times.
His opportunity cost would be <highest money>-<lowest money>=1000-750=250 dollars a month. Good luck on this question, and feel free to ask further questions!
Percentages and fractions so if you had to write 45 as a percentage it would be 45% and if you had to write it as a fraction it would be 45/100. In this case, you have 53.02 so as a percentage it would be 53.02% and as a fraction it would be 53/100. Hope this helps!!
For a direct variation, f(x) = kx. Therefore, for f(x) = 30x, constant of variation (k) = 30.

Answer:
11.2$
Step-by-step explanation:
Kristina and Melissa had 32$ at total

They have spent 35%
Let x be that amount
