Carla spent two-fifths of her savings on a bracelet and had $\$ 9$ left over. How many dollars did Carla's bracelet cost?

ololo11 [35]

Answer:

The cost of the bracelet was $\$6$

Step-by-step explanation:

Let

x------> amount of Carla's savings

y-----> the cost of bracelet

we know that

$y=\frac{2}{5}x$ -----> equation A

$1-\frac{2}{5}=\frac{3}{5}$

$9=\frac{3}{5}x$ ----> solve for x

$x=9*5/3=\$15$

substitute the value of x in the equation A and solve for y

$y=\frac{2}{5}(15)=\$6$
