Martin elementary school is organizing a school picnic, for which 47 students sign up. then, 21 more students sign up. the school hires vans for the picnic. one full van can carry 7 students.

how many vans should the school hire to take all the students who have signed up for the picnic?

10 vans

Step-by-step explanation:

well when you add 47 and 21 you get 68. 68 divided by 7 is 9.7 and well you cant have 9.7 vans so your best bet is 10. hope i did this right lol.

12 Vans

Step-by-step explanation:

I am taking the test. I clicked on 10 and got it wrong.

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:

true !
