Question

A bottle of 150 vitamins cost $5.25. If the cost varies directly with the number of vitamins in the bottle,what should a bottle with 250 vitamins cost?

Answer 1

Answer: $8.75

Explanation:

Set up a proportion where x is the cost of a bottle with 250 vitamins:

150/ 5.25 = 250/x

Cross multiply and solve for x

150x = 1312.5

x = 8.75

So, it will cost $8.75 for a bottle with 250 vitamins

x = 8.75

So, it will cost $8.75 for a bottle with 250 vitamins
