Britney already owns 65 necklaces, and additional necklaces are priced at 2 for a dollar. How much money does Britney need to spend on new necklaces in order to own a total of 133 necklaces? Write and solve an equation to find the answer

Step-by-step explanation:

First, we subtract 133-65 to find out how many new necklaces she need to buy

The answer is 68

Now, two necklaces costs $1, meaning one necklace costs ¢50, or $0.50.

So, we just multiply the number of necklaces (68) by the cost per necklace (0.5)

68×0.5=34

she will need to spend $34 to have a total of 133 necklaces

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
