There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

Answer:

$78.72

Step-by-step explanation:

To find 30% of the original value, we need to turn this percentage into a decimal or a fraction and then multiply it by the original value

  • 30% is equivalent to 0.30, \frac{30}{100}, and \frac{3}{10}
  • So we can use either of these values. I will use 0.30 for simplicity

  • ($262.40)(0.30) = $78.72 is the amount saved
