PC Solutions sells regular keyboards for $84 and wireless keyboards for $105. Last week the store sold 3 times as many regular keyboards as wireless. If total keyboard sales were $4998, how many of each type were sold?

Respuesta :

JiakSai

wireless keyboard sold = x

regular keyboard sold = 3x


105x + 84(3x) = 4998

105x + 252x = 4998

357x - 4998

x = 14 <============ Number of wireless keyboard

3x = 3(14) = 42 <============ Number of regular keyboard
