donovan. and three friends go to a fair they each spend 1/2 of their money on rides. then, they each spend $3 on food. at the end of the day, donovan and his friends have a total of $8 remaining how much money did each person spend

Answer:Each person spent $10.Step-by-step explanation:Let the money spent by each friend = $x Number of persons including Donovan = 4Total amount spent by all friends all together = $4xSince each spent half of their money on rides so amount spent on rides = [tex]\frac{4x}{2}[/tex] = $2xThen they each spent $3 on food so total money spent = $(2x + 12)Remaining money = $8Now the equation will be $4x - $(2x + 12) = $8 4x - 2x - 12 = 82x - 12 = 82x = 12 + 8x = $10Therefore, each friend spent $10.
