The future engineers of america treasurer was going back through the fundraising records. on monday, the club made revenue of $140 selling contest tickets at $10 each .one person sold 8 tickets, but the other person selling that day forgot to write down how many she sold. write and solve an equation to determine the number of tickets the other person sold

10(8) + 10 (x) = 140 80 + 10x =140 Subtract 80 both sides  10x= 140-80  10x = 60  Divide 10 both sides  10x /10 = 60 /10 X = 6   Therefore other person sold 6 .  To check  80 + 60 = 140

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

it is c, trust i got your back lol
