What can you say about the 3's in the number 43,335
kolbaska11 [484]
I assume it's 43 <em>thousand</em> and 335, not 43 <em>point</em> 335.

The first 3 from the right is for tens, the second is 10 times stronger because it's for hundreds and the fourth is again 10 times stronger because it's for thousands. Hopefully that's what you meant :)

14. Team 8A is selling snacks at the football game to raise money for a field trip. They are selling popcorn for $2.50 and pretz
Mamont248 [21]

Answer:

  • 40 popcorns and 90 pretzels sold.

============

Let the number of popcorns is x and pretzels is y.

Set up equations:

  • x + y = 130
  • 2.5x + 2y = 280

Solve by elimination, multiply the first equation by 2 and subtract from the second equation:

  • 2.5x + 2y - 2x - 2y = 280 - 2*130
  • 0.5x = 280 - 260
  • 0.5x = 20
  • x = 20/0.5
  • x = 40

Find y:

  • 40 + y = 130
  • y = 130 - 40
  • y = 90
