\[\boxed{80\text{ р. и }10\text{ р.}} \qquad \boxed{60\text{ р. и }10\text{ р.}} \qquad \boxed{70\text{ р. и }30\text{ р.}}\] За краски, альбом и кисточку Миша заплатил 90 р. Краски стоили \({\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{60}}\kern0.035em}}\) р., а кисточка — \({\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{10}}\kern0.035em}}\) р. Сколько стоил альбом?
\(1)\ 60 + 10 = \textcolor{#e03131}{\mathbf{70}}\text{ (р.)}\)
\(2)\ 90 - 70 = \textcolor{#e03131}{\mathbf{20}}\text{ (р.)}\)
Ответ: \(\textcolor{#e03131}{\mathbf{20}}\) р.
