Question

Please help me answer this question.

Answer 1

$\bf \textit{hmm how much is 0.25 of the pizzas?}\quad 0.25\cdot 40\implies \boxed{10}\leftarrow Ronnie \\\\\\ \textit{we know Mack stacked only \boxed{9}} \\\\\\ \textit{what is the 35\% of 40?}\quad \left(\frac{35}{100} \right)\cdot 40\implies \boxed{14}\leftarrow Kim \\\\\\ \textit{how many remain?}\quad 40-(10+9+14)\implies \boxed{7}\leftarrow Ada$

so.. that's how many each did, surely you'd know who did the most pizzas.
