Question

1. noah bought 6 bracelets for $8.28. at this rate:

a. how many bracelets could he buy with $13.80?
b. how much do 14 bracelets cost?

Explanation:

Part a

Step1: Find cost per bracelet

First, we find the cost of one bracelet. If 6 bracelets cost $8.28, then the cost per bracelet \( r \) is given by dividing the total cost by the number of bracelets. So, \( r=\frac{8.28}{6} \).
Calculating that, \( \frac{8.28}{6} = 1.38 \) dollars per bracelet.

Step2: Find number of bracelets for $13.80

Now, to find how many bracelets (\( n \)) can be bought with $13.80, we divide the total money by the cost per bracelet. So, \( n=\frac{13.80}{1.38} \).
Calculating that, \( \frac{13.80}{1.38}=10 \).

Step1: Find cost per bracelet (same as part a)

We already found that the cost per bracelet \( r = \frac{8.28}{6}=1.38 \) dollars per bracelet.

Step2: Find cost of 14 bracelets

To find the cost of 14 bracelets, we multiply the number of bracelets (14) by the cost per bracelet (\( r \)). So, the total cost \( C = 14\times1.38 \).
Calculating that, \( 14\times1.38 = 19.32 \) dollars.

Answer:

10
