Question

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.

The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.

Answer 1

equation: 20/c= 3.00c

Answer 2

Kenzie can buy 48 Scrunchies

Step-by-step explanation:

You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.
