Mona brought 20 cookies to share in class. Jasmine brought 5 fewer cookies than Mona. Rachel brought 10 more cookies than Jasmine. How many cookies altogether did Mona, Jasmine, and Rachel bring to share in class? Let's be accurate as possible.
Jasmine brought 20 - 5 = 15 cookies to class. Rachel brought 15 + 10 = 25 cookies to class. Mona, Jasmine, and Rachel brought 20 + 15 + 25 = 60 cookies.
The answer: 60.
