Question

The number of braclets collen can make varies directly with the amount of time she spends making the braclets. She can make 5 braclets in 2.5 hours. How many braclets can she make in 10 hours?

Answer 1

20

Explanation:

Collen makes 5 bracelets in 2.5 hours and you want to know the number she can make in 10 hours at that rate.

Proportionality

When a relation is proportional, increasing one value by a given factor means the other value also increases by that factor.

10 hours is 4 times 2.5 hours, so the number of bracelets Collen can make will be 4 times 5, or 20 bracelets.

Collen can make 20 bracelets in 10 hours.
