Question

Need help!! You can buy 10 yogurts for $6.50. How much would it cost for nine yogurts!?

Answer 1

To solve this problem, you should find the rate --->  cost per yogurt (cost/yogurt)

$6.50/10 yogurts = $0.65/yogurt

It costs $0.65 per yogurt, so you can multiply 9 by $0.65 to find the total cost of 9 yogurt.

9(0.65) = $5.85
