ответ:

94 афиши.

пошаговое объяснение:

производительность первого расклейщика равна 49 афиш/час

производительность второго расклейщика равна 38 афиш/час

формула для вычисления работы:

a = v * t, где a - работа, v - производительность, t - время.

найдем работы первого (a₁) и второго (а₂) расклейщика за указанное время (8 ч):

a₁ = 49 * 8 = 392 афиши;

а₂ = 38 * 8 = 304 афиши.

найдём совместную работу (а) обоих расклейщиков за 8 ч:

а₁ + a₂ = 392 + 304 = 696 афиш.

найдем, сколько афиш останется расклеить после 8-часовой совместной работы:

790 - 696 = 94 афиши.
