Question

A 2-lb bag of brown rice costs six dollars. How much would you expect to pay for a 5-lb bag of brown rice, assuming there is no discount for buying a larger bag?

Answer 1

2.5 times 6 dollars. this is because the new bag is 2.5 times larger than the 2lb bag! so just multiply by 2.5!

Answer 2

2 :6 = 5 : y
2y = 30
y = 15 dollars
