Question

I got 4 sandwiches for 10 dolers

. at this constant rate how much it cost me to buy 6 sandwiches

Answer 1

15 sandwiches
6/4 is 1.5 and 10 times 1.5= 15

Answer 2

15

Explanation:

4 plus 2 (half of four) is 6, meaning 10 plus 5 (half of ten) is 15. You take the 6 and the 15 and buying 6 sandwiches would be 15 dollars. (I might be wrong but I don't think so)
