Question

Megan buys 3 bracelets and 3 necklaces. Each bracelet costs 5. Megan pays on 40 and gets 4 change. what is the cost of one necklace?

Answer 1

Step 1: write equation

3(5)+3x=40-4

Step 2: simplify

15+ 3x= 36

Step 3: subtract 15 from both sides

3x-15=36-15

3x= 21

Step 4: get x alone

3x/3=21/3

x=7

Based on the data, each necklace is worth $7.00

don't forget to check!

3(5)+3(7)=36
15+21=36
36=36
